I don't know if it was the same concert or the one that was meant to be after it, but I remember them saying something like the place they were supposed to play was really crappy with broken glass on the floor and stuff. Sounds like everything came together and it was time for a break.
No problem! I think they've said they were all burnt out/exhausted at the time but Mike's health being affected by it to that extent was just too much, and it was a well needed break for all of them.
I completely understand your point, actually I feel the same, but I know that if I knew, I wouldn't be prepared for anything. I'd just worry more - about something I could do literally nothing about
