One morning in 1970 I was in my dressing room at the Royal Court, where I was appearing in Michael Blakemore’s production of Shaw’s Widowers’ Houses. I’d forgotten that the next play, Home, by David Storey, was being rehearsed during the day. Over the speakers I heard the unmistakable voices of Ralph Richardson and John Gielgud. It occurred to me that these two had totted more time on the London stage than would ever be equalled – I was listening to history.
