Delia produced electronic music and effects for the BBC's 1970 production of The Bagman or The Impromptu of Muswell Hill, a radio play by John Arden, directed by Martin Esslin. The presenter for a repeat broadcast says: "In it, in the form of a dream, some of the problems facing a socially conscious playwright in our time are described."
The play is one hour and 28 minutes in length and is described as a "Witty Fable" and a "modern version of Molière's Versailles Impromptu".
John Arden has a dream in which he meets an old woman who sells him a canvas bag, "A pig in a poke", he then finds himself transported to a dystopian land where the people are starving while the rich live in idleness and squalor.
A note in her papers says that The Bagman was entered by the BBC for the Italia Prize 1970 and that she was scheduled to receive 20% of the prize money if the play should win.
