John Simon Ritchie-Beverley (May 10, 1957 – February 2, 1979), better known as Sid Vicious, was an English punk rock musician and member of the band the Sex Pistols. He died of a heroin overdose at the age of 21. In November 1977 Ritchie met American groupie Nancy Laura Spungen and they immediately began a relationship (Spungen had come to London looking for Jerry Nolan of The Heartbreakers). She was a heroin addict, and inevitably Ritchie, who already believed in his own "live fast, die young" image, soon shared the dependence.
