High Quality Content by WIKIPEDIA articles! "Shine On You Crazy Diamond" is a nine-part Pink Floyd composition written by Roger Waters, Richard Wright, and David Gilmour. The song is a tribute to former band member Syd Barrett, although it was not originally explicitly written with him in mind. It was first performed on their 1974 French tour. It was recorded for the 1975 concept album Wish You Were Here. The song was 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.
