Eric Idle later played a videotape of the Rutles sketch on Saturday Night Live in 1976 during an appearance as guest host, and the favourable response led to a 1978 American-made spin-off TV movie, All You Need Is Cash, with Innes and Idle again playing Nasty and McQuickly. While Idle and Innes co-created the original Rutles sketch concept, Idle wrote the screenplay for the film on his own, and Innes composed all of the songs for the project without any input from Idle (Dirk McQuickly's musical contributions on the soundtrack were performed by guitarist/vocalist Ollie Halsall while Idle lip-synched them in the film). Innes' songs consequently appeared on the soundtrack album The Rutles, released by Warner Bros in 1978.
