I'm Sorry I Haven't a Clue

Humphrey Lyttelton, primarily known as a jazz trumpeter and bandleader, and known as Humph to his friends, was invited to be chairman because of the role played by improvisation in both comedy and jazz music.[15] In the first series Lyttelton shared the role of chairman with Barry Cryer[2] but he made it his own (especially once Cryer replaced Cleese as a regular panellist) and continued as chairman until his death on 25 April 2008.[16][17] He read the script introducing the programme and segments in an utterly deadpan manner. He claimed the secret was just to read what was in front of him without understanding why it was funny. He adopted the grumpy persona of someone who would really rather be somewhere else, which he attributed to worrying that, surrounded by four professional comedians, he would have nothing worthwhile to chip in. He did occasionally depart from the script, however, often bringing the house down with an ad-lib.[18] He was credited by the regular panellists as being the chief reason for the show's longevity.[19]

On 18 April 2008 the producer of I'm Sorry I Haven't A Clue, Jon Naismith, announced that, owing to hospitalisation to repair an aortic aneurysm, Humphrey Lyttelton would be unable to record the scheduled shows and that they would have to be postponed. The final show of the 2008 Best of tour on 22 April would be presented by Rob Brydon.[20] Following Lyttelton's death there was speculation that the series might be cancelled because replacing him would be extremely difficult if not impossible.[21] In a eulogy in The Guardian, Barry Cryer did not allude to the future of the programme but said that there's "got to be an agonising reappraisal" and that Lyttelton was the "very hub of the show".[22] Cryer, Tim Brooke-Taylor and Graeme Garden all ruled themselves out as hosts: Cryer did not think the programme would work if a panellist became chairman and it "would need somebody of stature to be parachuted in".[23] Jeremy Hardy also ruled himself out, saying "Humph had big shoes to fill and I wouldn't do it."[24]

In the Clue mailout for September 2008 Naismith stated: "Despite the rumours, we've made no decisions about possible replacements for Humph, and are unlikely to make any decisions this year at least. Certainly I don't envisage us selecting anyone on a permanent basis for several series."[25] It was announced that the show would continue recording beginning in 2009. The first new shows would be hosted by rotating guest presenters (similarly to the format of Have I Got News for You) before a permanent replacement host was decided.[24] In the Clue mailout for February 2009 Naismith announced that Stephen Fry, Jack Dee and Rob Brydon would host two shows each, to be recorded in April, May and June 2009 respectively.[26] The programme returned on 15 June 2009, chaired by Fry with the usual panellists and special guest Victoria Wood. Every series since then has been chaired by Dee.

The regular panellists for much of the show's history were:

• Graeme Garden was a member of the I'm Sorry, I'll Read That Again team from which the programme grew and has been a panellist since the first episode. Lyttelton described him as very dry, biding his time before stepping in with a perfect punchline.[27] Garden was absent from January 2016 for the whole of series 65, 66 and 67.[28][29][30][31] On 12 October 2017, Garden announced that he would be rejoining the team,[32] but has only appeared infrequently since then. Following the death of Barry Cryer, Garden is the last surviving original panellist.
• Barry Cryer hosted six episodes in the show's first series before moving to a permanent seat on the panel. He was credited by then-chairman Lyttelton as being the show's "bricks and mortar", providing quick-fire one-liners in any situation.[27] There is a running joke in the programme that he is a dirty old man with a drink problem. He died aged 86 in January 2022.[13]
• Tim Brooke-Taylor was also part of the I'm Sorry, I'll Read That Again team and was also with the show from the start until his death in April 2020. He was very popular with the crowd and adopted a vulnerable persona.[27] Garden and Brooke-Taylor had previously worked together on television in The Goodies and Brooke-Taylor in particular would occasionally drop references to that show into some of the games, eliciting cheers from the audience.
• Willie Rushton was one of the regular panel members from 1974 until his death in 1996. The other panellists have fond memories of his off-the-wall sense of humour and quick-fire puns.[13] Since Rushton's death his seat has been turned into a permanent guest spot, which was often filled by the late Jeremy Hardy when on non-broadcast tours. Guests have also appeared when one of the regulars was unavailable.

The show has had a number of producers over the years:

• David Hatch (produced only the pilot episode in 1972)
• John Cassels (1972–74)
• Simon Brett (1975–77)
• Geoffrey Perkins (1978–81)
• Paul Mayhew-Archer (1982–86)
• Paul Spencer (1987–89)
• Jon Magnusson (1990–91)
• Jon Naismith (1991–present)

Early episodes featured Dave Lee, who provided piano accompaniment on I'm Sorry, I'll Read That Again. However, Colin Sell now usually fills this role. He is often the butt of jokes about his musical ability, to which he is unable to respond as he has no microphone.[33] For example: "When music experts hear Colin's compositions, they say he could have been another Berlin, Porter or anybody else employed by the German State Railway." Guest pianists are called in when Sell has been unable to attend (or the ISIHAC team have "won the coin toss" as Lyttelton once said on the show), including Neil Innes, Denis King and Matthew Scott. Lyttelton's band also appeared on a couple of Christmas specials.[13] On one occasion when Innes was guesting, Lyttelton outlined the musician's career, concluding that this "has brought him to where he is today: standing in for Colin Sell." In another appearance Innes sang along to his own composition "I'm the Urban Spaceman" during a round of "Pick Up Song".[34]

The theme music is called "The Schickel Shamble", by Ron Goodwin, and is from the film Monte Carlo or Bust! It was chosen by David Hatch.[19]

Since 18 May 1985 (in the episode in which Kenny Everett made his debut), the show has included a fictional and completely silent scorer "whose job is eased by the fact no points are actually awarded". Usually this is "the lovely Samantha", who sits on Humph's left hand. There is a seat with a microphone next to the Chairman which is "used" by Samantha. During the introductory music, Humphrey Lyttelton would stand up and "help" Samantha into her seat. In practice, the seat and microphone were only used by the producer to welcome the audience, to introduce the participants and to give any other information to the audience such as the expected date of broadcasting, and to supervise re-recordings of fluffs made in the programme.

Lyttelton would describe Samantha's social activities, usually in an apology received from the unseen character who had been detained, often with a "gentleman friend". His comments included sexual innuendo and double entendres, like "Samantha likes nothing better than a little potter in the woodshed in the morning", though many were far more daring and explicit. During early episodes of Samantha's appearance on the show, it was not completely clear that she was a fictional character, garnering complaints about the sexist and humiliating treatment she received. Producer Jon Naismith recalled "when we [Naismith and Iain Pattinson] took over the show we used to get quite a few letters accusing us of sexist references to Samantha"[35] (the character was named after the page 3 topless model Samantha Fox).[36] Samantha's inabilities as score-keeper often form the basis for humour; in a programme from 1997, Humph said: "It's just occurred to me that Samantha hasn't given us the score... since 1981."

Samantha has sometimes been replaced by a Swedish stand-in, Sven, or occasionally another substitute, Monica.[13] When Margaret Thatcher left office in 1990 Lyttelton introduced a scorer named Margaret. In an episode in November 1991 both Samantha and Sven were present but occupied with each other and unable to award points.

The programme's scoring is completely non-existent. Most of the show is scripted, but in rounds such as "Sound charades", where one team of panellists have to guess the charade of the other team, the answer may be obvious (usually a pun) but the opposing team are not told the answer. In recording, it has taken them many minutes to come up with the correct answer, most of which has to be edited out before broadcast.

In rounds in which the panel must not see what the audience sees, there is the "advanced laser display-board" (in reality, a sign with the answer written on, held by Jon Naismith). These boards are sometimes described in more elaborate terms and as "so generously funded by our hosts". The names and phrases on them are conveyed to "listeners at home" by the "mystery voice", alluding to the 1960s radio programme Twenty Questions.

A regular feature on the programme, preceding the game Mornington Crescent, is a fictional letters section which begins with the chairman's comments ("I notice from the sheer weight of this week's postbag, we've received a little over no letters" and "I see from the number of letters raining down on us this week that the Scrabble factory has exploded again"). The invariably single letter each week is from "A Mrs Trellis of North Wales" (one of the many prompts for a cheer from the audience), whose incoherent letters usually mistake the chairman for another Radio 4 presenter or media personality. "Dear Libby" (she writes), "why oh why ... very nearly spells YOYO", or "Dear Mr Titchmarsh, never let them tell you that size isn't important. My aunt told me that, but then all my new wallpaper fell off."

The chairman introduces the show.

Many games are played on I'm Sorry I Haven't a Clue, some frequently and dozens less often. A few have been played only once, either because the joke works only once or because they were not particularly successful. Popular games include "One Song to the Tune of Another", "Mornington Crescent", "Sound Charades", "Late Arrivals", "Double Feature", "Cheddar Gorge" and "Uxbridge English Dictionary". "One Song to the Tune of Another" is always introduced using a complex analogy, despite its self-explanatory title, often ending with a joke at the expense of Colin Sell.

Most episodes follow a format, and the same games are played in sequence in most series. The first, third and fifth episodes of a series (recorded first of two shows in each location) usually includes "One Song to the Tune of Another" as its second round, and the alternate episodes feature "Pick-up Song" in the same slot. "Uxbridge English Dictionary" usually begins the second recording session, and the same session will usually include "Mornington Crescent". "Sound Charades" is typically featured in the odd-numbered episodes. This pattern is more consistent in later episodes.

The panellists play as individuals or as two teams. "Celebrity What's My Line?" completely destroyed the intent of the original — for players to guess the occupation of a third party by asking yes/no questions. The I'm Sorry I Haven't a Clue version once employed the famous actress (and fan of the show) Dame Judi Dench in this role and the renowned television gardener Alan Titchmarsh. Each began by performing a mime illustrating their occupation, giving a cryptic clue to the panel (appearing to a radio listener as a short silence punctuated by exclamations from the panel and laughter from the studio audience), before fielding apparently serious questions from the teams (e.g. "Is that your own hair?" or "Do you kill people for money?"), who pretended not to know who they were.

Musical games often involve incongruities such as singing "One Song to the Tune of Another" or playing a song using only a swanee whistle and a kazoo. In "Just a Minim" – a parody of Radio 4's Just a Minute – panellists must sing a specified song avoiding repetition, deviation, or hesitation: the chosen songs often have extremely repetitive lyrics.

Humour is derived from wordplay[11] such as puns or mockery of styles of speech. For example, in a round based on suggesting television programmes from biblical times:

• They Think It's All Jehovah
• I Love Lucifer
• The Exodus Files

In "Uxbridge English Dictionary" the panellists contribute humorous redefinitions of words; "Puny: the Roman Catholic equivalent of tennis elbow". More puns are found in the "Arrivals at the Ball" section, of the form "Mr and Mrs X and their son (or daughter)...." the child's name forming a pun, preferably laboured and feeble. This grew out of the "drama" section of later shows in the I'm Sorry, I'll Read That Again series, for example, at the Criminals' Ball, "Mr and Mrs Knee, and their Swedish son, Lars Knee".

According to Tim Brooke-Taylor, twenty per cent of the show is ad-libbed. According to Willie Rushton, it is more like fifty per cent, but he didn't think that a bad thing.[37]

The show draws to a close with the chairman imparting some final words of wisdom intended to evoke time, destiny, fate and eternity, undercut with silliness. For example: "...And so, as the hunter of time blasts the moose of eternity, and the dairy counter worker of fate sighs and grabs her mop..." Lyttelton's final sign-off on the show, shortly before his death in April 2008, was:

And so as the loose-bowelled pigeon of time swoops low over the unsuspecting tourist of destiny, and the flatulent skunk of fate wanders into the air-conditioning system of eternity, I notice it's the end of the show.
