Simonon played bass on almost all of the Clash's songs. Recordings that he did not play on include: "The Magnificent Seven" and "Lightning Strikes (Not Once but Twice)" on "Sandinista!" (played by Norman Watt-Roy), "Rock the Casbah" on "Combat Rock" (played by Topper Headon), and 10 of the 12 tracks on "Cut the Crap" (played by Norman Watt-Roy). "Sandinista!" featured bass played by Jones or Strummer, some but possibly not all of which Simonon later re-recorded once he rejoined the sessions after filming "Ladies and Gentlemen, The Fabulous Stains". Also, when performing "The Guns of Brixton" live he switched instruments with Joe Strummer, because it was easier for him to sing while playing guitar, instead of bass as he sings lead vocals on this track.
