Bassist Nicholas Greenwood previously played in the Crazzy World of Arthur Brown in the late 60s, and later hooked up with Khan with Steve Hillage and Dave Stewart. He cut one solo LP for the Kingdom label in 1973, with Dick Henningham on organ and Eric Peachy on drums, both previously members of Khan.
A mainstay in the progressive scene, Steve Hillage's earliest work goes back to the Middle Earth club in the late 60s with Arzachel, playing alongside bands like Pink Floyd and Tomorrow. After a break to attend University, Hillage returned to music, first returning (ever so briefly) with Dave Stewart for the eponymous Kahn album before joining Kevin Ayers' Decadence. From there, he would spend the next three years in the classic Gong trilogy line-up where he would meet future partner Miquette Giraudy.
