The original members of Delta 5, Julz Sale (vocals/guitar), Ros Allen (bass) and Bethan Peters (bass), formed the band "on a lark" [1], but soon became a part of the thriving Leeds post-punk scene, and later added Kelvin Knight on drums and Alan Riggs on guitar. Combining feminist politics with a two-bass funk-punk sound (much in the style of another, more famous Leeds band, Gang of Four), they released in 1979 their debut single, "Mind Your Own Business". This song was later covered by Chicks on Speed, Le Shok and Pigface. Bethan Peters went on to play on Fun Boy Three's second album, 'Waiting'.
