'The hero of Otherwise Engaged only prefers brevity when he can't have complete silence – or rather a silence filled with music. Everything in the play flows from that simple fact, which can be confusing on the page unless the reader remembers that , though not uttering, the hero would be visible – highly visible, I like to think, on the stage. This treacherous relationship between stage presence and page absence was illustrated by the response of the play’s first producer who nearly rejected it on the grounds that there was no main part. What lines the hero had I pared down in rehearsal, and then to the bone during our week in Oxford. In previews in London I chipped away at the bone, until we were left with what I fondly assumed was the merest, if not the purest, marrow.' Simon Gray
Otherwise Engaged was first presented by Michael Codron on 30 July 1975, at the Queen's Theatre, London.
