Sheridan Morley, the director, says I'm to tell you? no, seriously, we'll be doing songs and sketches - including material by Harold Pinter, Alan Bennett and Peter Cook that hasn't been seen since the Fifties. They started off as sketch writers who worked for radio, so this is a way of seeing them before they became playwrights. We're wading through hours of material. We have to be brutal. If it's not funny enough, out it must go. Most of it stands up pretty well.
