The David Steinberg Show

The supporting cast featured a number of people who would go on to greater fame on SCTV, and many Steinberg cast members were, in fact, simultaneously working on the first season of SCTV, which debuted the same week as The David Steinberg Show. SCTV cast members doing "double duty" on Steinberg included Joe Flaherty, Dave Thomas and John Candy. Martin Short, also a Steinberg regular, would later become a cast member of SCTV, but not until 1982. (After he joined SCTV, Short portrayed Steinberg in an SCTV sketch.)[3]

SCTV stalwart Andrea Martin also appeared in a few episodes of The David Steinberg Show, but not as a regular.

The cast of the 1976-77 edition of The David Steinberg Show were:

• David Steinberg as himself, the genial but beleaguered host of a variety show.
• Bill Saluga as Vinnie DeMilo and as Ray J. Johnson. Vinnie is the owner of the nearby "Hello Deli", and David's chief confidante. The cigar-chomping Ray J. Johnson, a separate character, occasionally drops by the show (but never the deli) to interrupt David's monologues with his own rambling observations.
• Trudy Young as Margie, the friendly Hello Deli waitress.
• John Candy as Spider Reichman, the wide-eyed, hippie-ish bandleader. Candy also provided the voice of Vinnie's cook, who is frequently heard in the offstage Hello Deli kitchen, but is never seen onscreen.
• Joe Flaherty as Kirk Dirkman, a deliveryman who rather improbably becomes a network executive overseeing David's show.
• Martin Short as Johnny Del Bravo, David's obnoxious, narcissistic, talent-free cousin who is the "featured singer" on the show.
• Dave Thomas as James MacGregor, the show's excitable Scottish security guard.
• Blue as Bambi Markowitz, David's ditzy, incompetent secretary/assistant.
