What was Sid Vicious's real last name?

Sid Vicious's real last name was Ritchie.

He was born Simon John Ritchie in Lewisham, London, in 1957. Reference works also give variants such as John Simon Ritchie and note that he later used the surname Beverley, inherited from his stepfather Christopher Beverley. Despite those naming variations, Ritchie is the surname most closely associated with his birth identity and is the canonical answer to this quiz question.

Ritchie became known as Sid Vicious after joining the Sex Pistols in 1977. The nickname was reportedly supplied by John Lydon, who took it from Lydon's hamster, Sid. Before becoming the Sex Pistols' bassist, Ritchie was part of London's early punk social circle and was connected with figures around the King's Road scene.

The name is often confused with the surnames of other Sex Pistols members. Steve Jones played guitar, Paul Cook played drums, and Glen Matlock was the band's original bassist before Vicious joined. Vicious's time with the group was brief, but his image became one of punk rock's most enduring symbols. He died in New York in 1979 at age 21.
