The show was created by BBC Radio producer John Fawcett Wilson and Ronnie Barker and featured Barker together with Terence Brady and Pauline Yates and Gordon Langford at the piano.
The theme music was a short excerpt taken from Divertissement by Jacques Ibert.
Among the writers was Gerald Wiley, which was a pseudonym used by Ronnie Barker to submit material without using his own name.
Other writers for the series included Jim Eldridge, Spike Milligan and Harold Pinter.
