Actually, I was talking to Dan about possibly playing Ireland this tour, and he said that although they'd love to, it's not going to happen.
I can't really go into detail (not that I have much detail to go on myself, mind) but he seemed quite cheesed off that they weren't able to do it. It's just an inescapable part of the touring process that's the problem, and there's no way of getting around it. It's a pity, because I'd love them to come back too. Regardless, though, really glad you had a good time. I was there in spirit, even if my body was a good few miles north!
