I'm trying to find this out myself, but their message board on their website has been down for a while now.
Also, they're starting up their 'skeletons in the closet' tour next week I believe, with rare songs that the fans voted for them to play....so I'm HOPING that they mix some of these obscure songs into the Progpower setlist.
EDIT
I stand corrected, the 'tour' started yesterday, and now their message board is back up. I'll post a setlist on here when I get it.
(not that it necessarily will be what they'll do at PP...and most likely not be).
