Space Truckin'

When it was first performed live, the band appended an instrumental that was originally part of the song "Mandrake Root" from their first album but gradually evolved into a showcase for Jon Lord's Hammond organ and Ritchie Blackmore's guitar solos. This usually took the length of the overall song to over twenty minutes, and it was always performed as the last number of the main set. A good example of this arrangement can be found on the Made in Japan album, wherein Blackmore also quotes the "cello" solo of "Fools" off Fireball.

Jon Lord played his solo through a ring modulator or played some of it on an ARP synthesizer. Meanwhile, Ritchie Blackmore usually split the guitar solo into two halves, a quiet section with just drums, then a loud section with the full band. The second half was often when Blackmore would smash his guitar, play it with his feet or throw it into the air. One of the most infamous incidents where that happened was at the California Jam festival in 1974, where he dropped one guitar over the edge of the stage, smashed a second against a TV camera, then set his amplifier on fire, which then subsequently exploded.

When Deep Purple reformed in 1984, this extended arrangement was reworked, and later included snippets of other songs.

During the Man of All Ages tour, the final part of the song, which originally featured high-pitched screaming by Gillan (now 71), instead featured high-pitched guitar in the same key as his original vocals.

On the remastered version of their 1982 album Live in London (recorded in 1974), there is a 31-minute-long live version of the song. It consists of a lot of improvising from the band members and in one part of the song they play the main riff from "Child in Time".

• British heavy metal band Iron Maiden contributed a cover of "Space Truckin'" for the tribute album Re-Machined: A Tribute to Deep Purple's Machine Head to celebrate the 40th anniversary of Deep Purple's 1972 release Machine Head.[1]
• American thrash metal band Overkill did a cover of "Space Truckin'" for their 1999 cover-album, Coverkill.
• American guitarist Ace Frehley has covered "Space Truckin'" for his 2020 album Origins Vol. 2.[2]

• The song appeared in the film Lords of Dogtown,[3] the documentary Warren Miller's Dynasty and the video game Guitar Hero: Van Halen.
• The 1997 remix of the song was featured in the first and last episodes of Ash vs Evil Dead.[4]
• "Space Truckin'" played in orbit as a wake-up call for the Red Team on Flight Day 3 of the crew of STS-107; it was specially played for Mission Specialist Kalpana Chawla, who was later one of the seven crew killed in the Space Shuttle Columbia disaster. A fan of the band, she traded e-mails with group members while in space. Guitarist Steve Morse, vocalist Ian Gillan, bass guitarist Roger Glover, drummer Ian Paice and keyboardist Don Airey were recording Bananas when the disaster occurred. Chawla had taken three CDs onboard Columbia: Deep Purple's landmark 1972 album Machine Head, 1996's Purpendicular and Rainbow's 1979 album Down to Earth (Glover and Airey were members of Rainbow at the time). To honor her, Deep Purple closed Bananas with "Contact Lost".[5]
• "Basically, this is 'Smoke On The Water', but in space," remarked Tim Wheeler of Ash. "All Deep Purple's songs seem to be about being in a gang and, true to form, this is too – but, this time, they're intergalactic travellers. The lyrics are utter nonsense, but it doesn't matter. It's just a real stomper of a song with a great riff. I like Jon Lord's organ sound. It's so distorted, it's like a guitar."[6]
