"Silly Thing" is a song by the Sex Pistols that was released in 1979. It was the 3rd single released in promotion of the film The Great Rock 'n' Roll Swindle. It was written by drummer Paul Cook and guitarist Steve Jones, and recorded after the band's original lead singer, Johnny Rotten, left the band. Typically, Jones also played bass in the studio, rather than suffer the ineptitude of the band's official bassist, Sid Vicious. Essentially, it's a Cook/Jones recording more than a true band's work.
