BBC Radio 2 - Darkside

Pink Floyd 2013-08-26 Darkside by Tom Stoppard [mp4]

The play was broadcast at 10 p.m. Here's the description from the Radio 2 website:

"A new drama from legendary playwright Sir Tom Stoppard, to celebrate the 40th anniversary of Pink Floyd's The Dark Side of the Moon. The album topped the charts on its release in 1973, and it remained in the charts for 741 weeks from 1973 to 1988. With an estimated 50 million copies sold it is the band's most commercially successful work and is frequently ranked as one of the greatest albums of all time.

Sir Tom Stoppard was first approached with the suggestion of writing a play based on the album by a friend in 1973. Now, 40 years later, he's created a fantastical story about fear, philosophy and madness, which is woven together with the original music."
