I understand taking a break and cleaning up when a pigeon shits in your mouth, but outright cancelling the concert seems a bit weak.

I'm biased though..everytime I hear or see about Kings of Leon it's negative. A while back they gave a concert here and they were pretty much shittalking the crowd. How they hate that people come to their concerts and only know one song that was a hit. Even if it's true that alot of people probably don't really 'know' you yet, that's one terrible way to treat your adience who have paid big money to see you perform.
Oh, and then they refused to come back for an encore.

I guess these bastards don't like being famous.
