Sid was not recognized as a competent bass player. During an interview for Guitar Hero III, when Sex Pistols guitarist Steve Jones was asked why he instead of Vicious recorded the bass parts of Never Mind the Bollocks, Jones responded, "Sid was in a hospital with hepatitis so he couldn't really play, not that he could play anyway."[13] Sid asked Lemmy, the bassist of Motörhead, to teach him how to play bass with the words, "I can't play bass," to which Lemmy replied "I know." In another interview Lemmy stated "Yeah. It was all uphill. And he still couldn't play bass when he died."[14]
According to Paul Cook, in the few months between joining the band and meeting Nancy, Sid was a dedicated worker and tried his hardest to learn to play; indeed, this period was Cook's favorite in the band.[15] Viv Albertine went further in defense of his ability, saying that one night she "went to bed, and Sid stayed up with a Ramones album and a bass guitar, and when I got up in the morning, he could play. He'd taken a load of speed and taught himself. He was so quick." [16] Keith Levene, a member of The Flowers of Romance with Sid and later a member of The Clash and then Public Image Ltd, also recounts a similar story, "...Could Sid play bass? I don't know, but one thing I do know, was that Sid did things quickly. One night, he played the first Ramones album nonstop, all night, then next morning, Sid could play the bass... that was it, he was ready! I told you, Sid did things quickly!"
