The pink floyd story: which one's pink? (2007)

Forty years after Britain's foremost 'underground' band released their debut album, 'Piper At The Gates Of Dawn', Pink Floyd remain one of the biggest brand names and best-loved bands in the world. This film features extended archive footage alongside original interviews with David Gilmour, Roger Waters, Richard Wright and Nick Mason, and traces the journey of a band that has only ever had five members, three of whom have lead the band at different stages of its evolution.
