The original members of Delta 5, Julz Sale (vocals/guitar), Ros Allen (bass) and Bethan Peters (bass), formed the band "on a lark", 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".
