"Shine On You Crazy Diamond" is a nine-part composition by the English rock band Pink Floyd for their 1975 album Wish You Were Here. It was written by David Gilmour, Roger Waters, and Richard Wright, and first performed on Pink Floyd's 1974 French tour. The song is written about the Pink Floyd founder member Syd Barrett, who left in 1968 following mental health problems. Background The song originated from a riff composed by the guitarist David Gilmour and developed by Gilmour, bassist Roger Waters and keyboardist Richard Wright. It was conceived and written as a tribute to the Pink Floyd founder member Syd Barrett. Barrett was eased out of the band in 1968 due to his substance abuse and deteriorating mental health, which impaired his ability to integrate with the other band members in creating and performing music. He was replaced by his former school friend Gilmour, who had initially been brought in as second guitarist. The remaining members of the band felt guilty about having removed him, but although they admired Barrett's creativity, they were concerned about his severe mental decline and felt it had been necessary. "Shine on You Crazy Diamond" was first performed on Pink Floyd's 1974 French tour and was recorded for their 1975 concept album Wish You Were Here. The track was originally intended to be a side-long composition, like "Atom Heart Mother" and "Echoes", but was ultimately split into two parts and used to bookend the album, with other newly composed material acting as a bridge.
