The 40th anniversary of Pink Floyd’s 1973 Dark Side of the Moon album is to be marked on BBC Radio 2 by an hour-long audio drama written by OP Sir Tom Stoppard (1951-1954). Dark Side, to air on 26 August later this year, will incorporate music from the album as part of its “fantastical and psychedelic” story according to a BBC report. The radio play will feature an all-star cast including Iwan Rheon, Amaka Okafor, Bill Nighy and Rufus Sewell. Floyd member David Gilmour said he had found Sir Tom’s script “fascinating”. He said “I can’t think of a better way to celebrate The Dark Side of the Moon’s 40-year anniversary,” said the guitarist and vocalist.
