"Sleak (aka Snuff Rock)", inspired by the then recent film, "Snuff", and the concept of snuff movies, but carrying the idea to a band who killed themselves for entertainment, was their musical play presented at London's Royal Court Theatre and Round House and was famous for the role of the comic disc jockey played by Les Prior. They reached the UK Singles Chart with the accompanying EP, "Snuff Rock", released on Stiff Records, poked fun at the punk rock phenomenon, targeting the Sex Pistols ("Gobbing On Life"), The Damned ("Kill") and The Clash ("Snuffin' Like That") as well as myriad reggae bands in "Snuffin' In A Babylon". Tony Bowers and Bob Harding left the band in July 29, 1978, they were replaced by John Scott (vocals, bass, guitar, saxophone, keyboards) (ex John Cooper Clarke and Jilted John) and Ged Green (vocals, guitar, bass, keyboards) in August 24, 1978. They reached the UK Singles Chart with the Status Quo spoof, "Heads Down No Nonsense Mindless Boogie" in 1978. Les Prior died in January 1980 from leukaemia, which left a large gap in the group. Ged Green left the band in March 27, 1980, he was replaced by Ian Morris ("Mog") (vocals, bass) (ex The Smirks) in March 28, 1980.
