I'm also sure they had justification. I don't really see the point of this thread, it's immature and unnecessary. If you have a problem with the band's decision, try contacting them privately, instead of whining to everyone here.
Sorry, I can imagine you feel upset, but I'm sure you'll get to see them play sometime. Just be happy that you heard the band in the first place, whereas many unfortunate people have not. They're decent, honest guys, they don't toy with their fans, they surely have a reason for pulling out.
I'm hoping that this doesn't turn into another silly hostile thread...
