They used to play in Vancouver a lot so I've seen them a bunch of times. The first time, they were incredible, second time, really really good and then it just went downhill each time. The last time was kind of cringe-y: the exactly the same schtick, word for word, same cover riffs in the guitar solo, 15 minutes wasted trying to get girls to get their tits out etc. You can do that once or twice, but not if you play in the same city for the same people every couple of months.
And so, for me, the joke has got old and the music isn't a patch on what they used to do. I think it's a great idea and they should ride it for all it's worth, but it's just not as good as it used to be - they're buying into their own hype..
