Rainbow Ffolly, an psychedelic art-rock band, evolved in High Wycombe, Buckinghamshire, in the 1960's from a group called Force Four. Jonathan Dunsterville picked the new name to conjure up the eye-searing colours associated with psychedelia, doubling the 'f' on Ffolly in tribute to Wally Ffolks, jazz clarinettist and creator of the 'Flook' cartoon strip. Roger Newell and Stewart Osborn were neighbours who had known each other since the age of three.
