Thanks everybody!
I guess the only people who know for sure are Scott, Dean, Robert and Eric, and they aren't revealing any set-lists.
I'm sure I'll enjoy the concert, but since I've already been to two STP concerts in 2009, I'll have to admit I will be a bit disappointed if little or no new music is played. At any rate, tickets are relatively cheap and the venue is great, so if they play mainly old classics, I'll enjoy them and pray they set up another date in my part of the country later on.
