 The shift from the experimental nature of the late 50s dramas to theme tunes was noticeable enough for one radio presenter to have to remind listeners that the purpose of the Workshop was not pop music.In fact, in 1962 one of Fagandini's interval signals "Time Beat" was reworked with assistance from George Martin (in his pre-Beatles days) and commercially released as a single using the pseudonym Ray Cathode.During this early period the innovative electronic approaches to music in the Workshop began to attract some significant young talent including Delia Derbyshire, Brian Hodgson and John Baker, who was in fact a jazz pianist with an interest in reverse tape effects.
