This week BBC Radio 6 are broadcasting a four-part documentary looking at the career of Pink Floyd. Starting yesterday and running until Thursday night is Wish You'd Been Here - The History of Pink Floyd, presented by Bob Harris.

The set of interviews are being broadcast to coincide with Roger Waters birthday yesterday, and form part of the radio station's "6 Music Plays It Again" series, which replays some of the best BBC documentaries about the bands who have shaped popular and alternative music in the past 40 years.

Each show is being broadcast between 2130hrs - 2200hrs BST (GMT+1), and 0300hrs - 0400hrs BST. As with many BBC shows, they offer the chance to listen again on demand via their website.
