The play was an original commission by Radio 2 to mark the 40th anniversary of Pink Floyd s album, and broadcast on 26 August 2013.Produced in collaboration with Sir Tom Stoppard s publishers Faber and Faber, the luxury package resembles a hard-backed book, including a CD carrying the 54-minute play, which includes the majority ofThe Dark Side of the Moonalbum, plus a 56-page bound insert of the play s script."Darkside" is an abstract and compelling drama which follows Emily, a philosophy student, through a series of thought experiments, which are vividly brought to life. The play also ranges over a series of grand themes, which are both thought provoking and laced with Stoppard s characteristic wit and humour. The cast is impressive, with Bill Nighy as Dr Antrobus/the Witch Finder, Rufus Sewell is Mr Baggott/Ethics Man, Adrian Scarborough is Fat Man and Emily is Amaka Okafor.David Gilmour: "I found the script of Tom s play fascinating; I can t think of a better way to celebrateThe Dark Side of The Moons 40 year anniversary."Nick Mason: "I love it. If anyone is going to mess with the crown jewel of albums, Tom is a very good choice. "The Dark Side Of The Moonremained in the charts for 741 weeks from 1973 to 1988. With an estimated 50 million copies sold, it is Pink Floyd s most commercially successful album and is frequently ranked as one of the greatest albums of all time.
