A great number of DJs joined Radio Kaleidoscope between 1967-1973, at least five of whom have gone on to be professional jockeys on commercial radio stations around the world, and who are still broadcasting today. Others still remain anonymous, as they never came to the studios to record their shows, preferring to post tapes through the letterbox. The vast majority of the Radio Kaleidoscope crew, too, have become professionals in a variety of specialist fields. Whilst every effort has been made to ensure that the list below is complete and accurate, there are a large number of people it has not been possible to trace, and some who have preferred to remain unnamed.
