Hmm I may be interested. I would probably have to take a day off of work though; or rather I'd like to do things that way so I can enjoy the concert more and not have to worry about geting home so that I can be up at 5 for work. If I can swing that day off I'd be all for it.
Leave the 20th, come back the 25th. I thought about trying to see if I can get my own ticket changed to leave on an overnight flight after the show or maybe the next day, but it's probably a lot of hassle and there's a good chance there's a hefty fee for changing flights.
Looks like I will be missing this one, and hoping they come back sometime within the next couple of years.
