I've seen worse.
When John Mellencamp was John Cougar Mellencamp ( that's just after Johnny Cougar) he was on Nightwatch, and after about 30 seconds, he was asked something that he didn't like he yelled out 'Howard, get me otta here! Howard!!!!?? Howard!!!??". (Howard must have been his manager.) Then he ripped the mike off his shirt and stormed off. What a ass! He can't act either.
About Canadian audiences: I saw the Stones (with Stevie Wonder opening) in 1972 at Maple Leaf Gardens, in Toronto. All of the natives sat in their chairs and were very reserved. It's a cultural thing. At least is was then. The Americans who came north for the show contained them selves for a while, but half way through, stormed the stage.
By the way, the Stones were all show biz and more than a bit of a boor to me. Stevie stole the show. I remember he played drums at one point too.
