This is classic Sum. They were supposed to play a show at the Six Flags in my town like 8 years ago but cancelled last minute.
It's been a lot worse in recent years though. Sum 41 played here 5 times between 2003-2005 and they never cancelled one show. They were supposed to play in 2007, but they cancelled. They were supposed to make up the 2007 show in 2011, but they cancelled again.
Surprise surprise... These guys are really starting to annoy me. I really feel like they should just retire already instead of cancelling all these tours and disappointing everyone. I know it's actual legitimate excuses but it's still an upset that I've experienced personally (2 years in a row at warped). I'd be disappointed I never got to see them, but it's a lot better than thinking your seeing them and finding out the day before that you aren't.
I agree. And in a lot of ways, some people may hate me for this, but I think they should have quit when Dave left. He played such a huge role in that band and they haven't been the same since.
