I haven't seen him either, but I heard he has a really great show. He has a lot of interaction with the audience from what I've read and tells funny stories between songs. I'd like to see him if he comes through Houston. My next concert is John Hiatt at the House of Blues in early December. I can't wait! I've been a fan since "Slow Turning" and I've never seen him live.
You're in for a treat then.
