800 - Pink Floyd Shine On You Crazy Diamond 1975

"Shine On You Crazy Diamond" is a nine-part Pink Floyd composition with lyrics written by Roger Waters in tribute to former band member Syd Barrett and music written by Waters, Richard Wright, and David Gilmour. 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 the song grew longer than a single side of vinyl would allow. It was split into two parts and used to bookend the album.
