I heard this tale about Alan Davies years ago;|
During a charity gig, where Davies was fiddling with the material of the curtain at the back of the stage, doing no stand up at all - the audience were getting restless and one shouted: "Tell us a joke Alan." He shook his head and as he still had the curtain in his hand someone else shouted: "Wrong material Alan." He then proceeded to storm off the stage and has never been back since.
Turns out to be true
