To anyone that is complaining, give the band a break.
Family should always come first, and if it is something serious then they should take all the time they need. I know it sucks when you've been looking forward to it for this long, but show the guys some respect. They're all really good guys, they wouldn't reschedule for no reason. And they haven't cancelled.. It's still going to happen.
I wish you and your families the best, and I hope everything works out.
