It was during the Broadway run of Good Evening that Cook persuaded Moore to take the humour of Pete and Dud further on long-playing records as Derek and Clive. Chris Blackwell circulated bootleg copies to friends in the music business and the popularity of the recording convinced Cook to release it commercially as Derek and Clive (Live) (1976). Two further "Derek and Clive" albums, Derek and Clive Come Again (1977) and Derek and Clive Ad Nauseam (1978), were later released. The latter was also filmed for a documentary, Derek and Clive Get the Horn. In the film it is clear tensions between the two men were at a breaking point, with Moore at one point walking out of the recording room singing, 'Breaking up is so easy to do.' In 2009, it came to light that, at the time, there were attempts to have them prosecuted under obscenity laws for their "Derek and Clive" comedy recordings.
