I was there as well. He didnt seem quite in a good shape to me. And when moving from one place to the other (especially in the Band only area), he was dragging his girlfriend by the arm. I later had a chat with him, and same thing, his gf was just standing idle and smiling.
Anyway, I'll be at the next gig with some friend for sure. The band is really good. Have you also noticed how some of their songs sounded like the Stones (Garden of Eden sounds like Jiving sister fanny, and at some point during the gig i thought they were performing a cover of Slave).
