Jones played bass on the two songs recorded after Matlock's departure, with Vicious also contributing to the song "Bodies". 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. In his autobiography, Rotten: No Irish, No Blacks, No Dogs, John Lydon stated that Matlock worked on Sex Pistols material (including their album Never Mind the Bollocks, Here's the Sex Pistols), after he had left the band, as a paid session musician. In the 2000 documentary The Filth and the Fury, the band members generally agree that there was tension between Matlock and Rotten, which Matlock suggests was further aggravated by Malcolm McLaren in an attempt to generate chaos within the band as a creative mechanism. In I Was a Teenage Sex Pistol, Matlock stated that he left the band of his own volition as he was "sick of all the bullshit". Another claim, made at the time by Jones, that he thought it bizarre that Matlock was "always washing his feet", has also been misquoted and misinterpreted as the cause of Matlock's firing from the group. The claim was fictional, with Steve Huey of AllMusic posthumously claiming that Matlock "was even more enamored of The Faces and the mod groups prominently featured on London pirate radio in the late '60s, as were Steve Jones and Paul Cook". Matlock left the band in late February 1977, with contemporary reports (given to news outlets by manager Malcolm McLaren) stating that he was 'thrown out' because he "liked the Beatles". Additionally, whilst Jones has insisted that Matlock disliked many of Johnny Rotten's controversial lyrics, Matlock has said that he had no issue with them. According to a 2014 interview, he played a big role in writing the songs that appeared on the album and Cook has stated that Matlock wrote most of the songs appearing on the album. However, his overall contribution to these songs has been disputed: Jones said in a 2011 interview he was "tired of Matlock's claims that he had co-written some of the punk icon's biggest tunes", stating that he himself had written as many songs as Matlock, whilst Matlock himself notes in his autobiography, I Was a Teenage Sex Pistol, that the band only wrote two songs after his departure. He is credited as co-writer on 10 of the 12 songs appearing on the album Never Mind the Bollocks, Here's the Sex Pistols. He was the original bass player of the Sex Pistols, having been introduced to guitarist Steve Jones and drummer Paul Cook while working in SEX, Malcolm McLaren's clothing boutique in London. Matlock attended Saint Martin's School of Art until 1974.
