X-Ray Spex are an English punk band from London that formed in 1976. The original line-up featured singer Poly Styrene (born Marianne Joan Elliott-Said) 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 latter instrument was an atypical addition to the standard punk instrumental line-up, and became one of the group's most distinctive features.
