Initially, the band featured singer Poly Styrene (born Marion Joan Elliott-Said) (alternatively spelled Marian or Marianne) on vocals, Jak Airport (Jack Stafford) on guitars, Paul Dean on bass, Paul 'B. P.' Hurding on drums, and Lora Logic (born Susan Whitby) on saxophone. This last instrument was an atypical addition to the standard punk instrumental line-up, and became one of the group's most distinctive features. Logic played on only one of the band's records. As she was only fifteen, playing saxophone was a hobby and she left the band to complete her education.
