Wow. I am so glad I shelled out the cash for the meet and greet! I am hammered but in Kiss' acoustic set they played the following that I can remember.
Hard Luck Woman
I Still Love You part of song
Do You Love Me
God of Thunder (Gene lost his voice so Paul, Eric and Tommy and crowd sang)
Possibly more songs but I cannot.remember. Will report later. Simply put amazing as I was 5 feet away during acoustic set
