Radio 2 celebrates the experimental and influential British band.
The four members of the classic Floyd line-up - David Gilmour, Nick Mason, Roger Waters and the late Rick Wright, in his last ever radio interview - tell their own story from pre-Floyd days in the early 60s, right up to Nick & David's live appearance with Roger earlier this summer.
In the second episode, the band discuss the album, tour and film of The Wall, before candidly exploring the tensions that led to the departure of Roger Waters in 1985.
They also touch on the Live 8 reunion and their appearance at the 2007 tribute concert for Syd Barrett.
This documentary first broadcast on Radio 2 in 2007 to coincide with the band's 40th anniversary.
It is presented by Janice Long.
It's brought up-to-date with Nick Mason also covering Rick Wright's death, the band's future and the live show he did with David and Roger in the summer.
