During the 1972 Edinburgh festival, I was part of the cast cooperative which mounted a financially reckless production of The Great Northern Welly Boot Show in the vast and long-demolished Waverley Market. It was partly written by, and starred, an up-and-coming Billy Connolly.
We gave Michael Rudman (Obituary, 30 March), who was running the Traverse theatre, a free ticket to our show and asked for his reaction.
