I'm not sure if I mentioned this...
The Rush show in Chicago on 7/7/10 (my birthday) was rained out ("Rain or Shine" on the ticket didn't count for this one) and rescheduled for late August. Upon leaving the show every person in the audience got a custom Rush "Rain Date Show 8-23-10" fitted baseball cap as a thank you for coming back and sorry for the inconvenience.
I've heard of them doing similar things for cancelled shows in the past (tour books, etc.) but how cool is that?
I just picked up the Blu-Ray today as well, I have to wait until morning to watch so I don't wake the family...
