Sid Vicious, born John Simon Ritchie, later named John Beverley, was an English bass guitarist and vocalist most famous as a member of the influential punk group the Sex Pistols. Vicious joined the Sex Pistols in early 1977 to replace Glen Matlock, who had fallen out of favour with the rest of the group. Due to intravenous drug use, Vicious was hospitalized with hepatitis during the recording of the Sex Pistols' debut album Never Mind the Bollocks. Accordingly, Vicious' bass is only partially featured on one song from the album. Vicious would later appear as a lead vocalist, performing three cover songs, on the soundtrack to The Great Rock 'n' Roll Swindle, a largely fictionalized documentary about the Sex Pistols produced by the group's former manager Malcolm McLaren and director Julien Temple. During the brief and chaotic ascendancy of the Sex Pistols, Vicious met eventual girlfriend and manager Nancy Spungen. Spungen and Vicious entered a destructive codependent relationship based on drug use. This culminated in Spungen's death from an apparent stab wound while staying in the Hotel Chelsea, Manhattan, with Vicious. Under suspicion of having committed Spungen's murder, Vicious was released on bail; he was later arrested again for assaulting Todd Smith, brother of Patti Smith, at a night club and underwent drug rehabilitation on Riker's Island. In celebration of Vicious' release from prison, his mother hosted at his girlfriend's Greenwich Village residence a party for him which was attended notably by the Misfits bassist Jerry Only.
