Never Mind the Bollocks, Here's the Sex Pistols is the only studio album by the English punk rock band the Sex Pistols. It was released on 28 October 1977 through Virgin Records. As a result of the Sex Pistols' volatile internal relationships, the band's lineup saw changes during the recording of the album. Original bass guitarist Glen Matlock left the band early in the recording process. While he is credited as a co-writer on all but two of the tracks, Matlock played bass and sang backing vocals on only one track, "Anarchy in the U.K."
