Be v-e-r-y careful ... somewhere in England many years ago, a young, snd slightly nervous, man with an electric guitar was doing his best to entertain his audience. The singing was ok, the guitar was so-so, the jokes were passable. But the was a heckler in the audience who obviously thought he was far more entertaining than the guy on the stage. Eventually the poor lad made the Fatal Mistake: "if you think you can do better, come up here and show us!" And he did, and he was better ... The guitarist was Sid Little and the heckler was Eddie Large, and they teamed up to become an object lesson to us all. Never let anyone on your stage unless you really know what you're doing!
