Sid Vicious, born John Simon Ritchie, later named John Beverley, was an English bass guitarist, drummer and vocalist, most famous as a member of the influential punk group the S** Pistols. Vicious joined the S** 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 band's only studio album Never Mind the Bollocks. Accordingly, his bass is only partially featured on one song from the album. ... more on Wikipedia
