Looks like there aren't any tickets for sale yet, but I'm sure there will be as it closer to the date of the concert!
One of the other people I was at the concert with, Jason, might have caught your sister's reaction on video; I can ask him. Jason is the guy that stopped by the after-party to return your vinyls to you. Your sister was really shocked though! If I remember correctly she said something like "what? what is he doing? I had not idea he was going to do this!" And then she turned to the guy she was with, I guess he must have indicated that he knew about it and she said, "what, you knew about this?!" She was so cute.
