I remember as if it was only a week ago (which it was) that I went to see Ken Dodd at the Wimbledon Theatre (which for some reason is now called the New Wimbledon Theatre). And yet I hardly remember any of his jokes. Not that he told that many - about five or six and they were nearly all in the second half. And yet he was on stage, making a packed theatre laugh non-stop from 7pm until just after 11pm with only a 20-minute pause for his support act (a relic from the days of variety, a lady trumpeter(!) who has supported him for years) and a 15-minute interval. So for about three and a half hours he had that audience by the scruff of its neck. Genius.
