<Tr> <Th> Producer (s) </Th> <Td> Pink Floyd </Td> </Tr> <P> "Shine On You Crazy Diamond" is a nine - part Pink Floyd composition written by David Gilmour, Roger Waters, and Rick Wright . It appeared on Pink Floyd's 1975 concept album Wish You Were Here . </P> <P> The song was conceived and written as a tribute and remembrance to their former band member Syd Barrett; the title of the song itself can also be seen as a reference to Barrett (Shine On You Crazy Diamond). The work was first performed on their 1974 French tour and recorded for their 1975 concept album Wish You Were Here . It was intended to be a side - long composition (like "Atom Heart Mother" and "Echoes") but was ultimately split into two sections and used to bookend the album, with new material composed that was more relevant to the album and to the situation in which the band found themselves . </P> <P> Bassist Roger Waters commented, as the sessions were underway, that "at times the group was there only physically . Our bodies were there, but our minds and feelings somewhere else ." Eventually an idea was raised to split the epic in two, Parts I--V and Parts VI--IX . </P>
