Part one of the song was called "Baby Blue Shuffle in D Major" when played by the band in a BBC broadcast on 2 December 1968;[2] it also strongly resembles the tracks "Rain in the Country (take 1)" and "Unknown Song" recorded (but eventually not used) for the soundtrack of Michelangelo Antonioni's film Zabriskie Point in November/December 1969. This portion features layered acoustic guitar with some spacey effects overtop.
Part Two (2:53)
Part two features an electric guitar and percussion which modulate heavily at the end, forming a drone that leads into part three.
Part Three (5:57)
Part three of the song features Gilmour's only vocal contribution to the studio part of the album.[3] This final part was incorporated into The Man and the Journey by the full band on their 1969 tour.
