and second guitarist, while Barrett, whose mental state and difficult nature were creating issues with the band, was intended to remain home and compose songs, much as Brian Wilson had done for The Beach Boys; however, this idea was soon abandoned. Barrett's unpredictable behaviour at the time and idiosyncratic sense of humour combined to create a song that, initially, seemed like an ordinary Barrett tune. However, as soon as the others attempted to join in and learn the song, Barrett changed the melodies and structure, making it impossible for the others to follow, while singing the chorus "Have You Got It Yet?" and having the rest of the band answer "No, no!". This would be his last attempt to write material for Pink Floyd before leaving the band. In fact, Waters stated, in an interview for The Pink Floyd and Syd Barrett Story, that upon realizing Barrett was deliberately making the tune impossible to learn, he put down his bass guitar, left the room, and never attempted to play with Barrett again. Waters had called it "a real act of mad genius". The song was never recorded by Pink Floyd or Barrett. Later–era unreleased songs "The Committee" Instrumentals In early 1968, Pink Floyd recorded several instrumental tracks to be used in the soundtrack to the Peter Sykes film The Committee, starring former Manfred Mann singer Paul Jones. Syd Barrett had originally been approached to record music for the film, but his solo attempt was deemed to be unusable. The band, now with Gilmour on guitar, took over and recorded their pieces in a basement studio in London. The two main pieces are actually the same tune played at two different tempos, with the main riff featured on guitar for the first, the keyboard for the second. A third, lengthy instrumental is an embryonic version of "Careful With That Axe, Eugene". The opening instrumental is a short backwards-played tape made up of Tablas, guitar and a high pitch sound effect, which sounds very similar to what was described by the makers as the piece Barrett had attempted, leading fans to believe his initial idea may have been used by the band. Parts 1 and 2 have seen official release in The Early Years 1965—1972 box set. "Richard's Rave Up" "Richard's Rave Up" was a track recorded on 13 February 1968, during sessions for A Saucerful of Secrets. Per Glenn Povey's The
