last time i saw JCC his mike was turned off,(i think he thought that he was being booed - but people were shouting ,we can't hear you etc) when he had finished,the compare (keith allen) managed to get the sound working and said - 'if you think the sound-man is a Cnut clap your hands,if you think the sound-man is a Cnut clap your hands'.... lots of hand-clapping ensued,
JCC, thought it was a request for an encore and obliged only to be told that there wasn't time.
