About Glen Matlock
Glen Matlock is an English musician and the bass guitarist in the original line-up of the punk rock band the Sex Pistols. He is credited as a songwriter on 10 of the 12 songs on the Sex Pistols' only officially released studio album, Never Mind the Bollocks, Here's the Sex Pistols, although he had left the band early in the recording process, credited as bassist and backing vocalist on only one song on the album, "Anarchy in the U.K." However, on the bootleg album Spunk, Matlock played bass on all the songs, which included earlier studio recordings of 10 of the 12 songs that later appeared on the Bollocks album. Under the moniker Rhode-Twinn, Matlock (and Steve New) was brought to play on Gary Twinn's 1990 single "Bike Boy" on Bernard Rhodes' own Sacred record label. However, Matlock denied the "session musician" label, stating that all but two of the songs appearing on the album had already been recorded as singles or b-sides before his departure. Jones played bass on the two songs recorded after Matlock's departure and overdubbed some additional parts on other existing songs, with Vicious also contributing to the song "Bodies". Music historian David Howard states that Matlock did not participate in any of the Never Mind the Bollocks recording sessions.
