(8) Shine on You Crazy Diamond (WISH YOU WERE HERE)

With all nine parts combined, its Pink Floyd's longest song clocking in at 25 minutes. In those 25 minutes, you feel the entire mood of Waters and the rest of the band after Barrett's meltdown. Years of comradeship and a bright spot of talent gone out like a candle fire, with Waters' vocals reflecting this loss, for Barrett was both admired, and quite missed.
