That's great that you'll have the opportunity to meet him!! What a thrill it is!! I met him the first time after a show and I don't think he was at 100%, as he'd had a surgery recently. His show was awesome as ever, but he seemed tired afterward. As always, he couldn't have been more gracious and sweet. I was nervous, and didn't really try to carry on much of a conversation. I was so tickled and thrilled to just be near him. He signed a couple of CD's and stood with me for pictures. He called me "sweetie" twice, and my heart fluttered.
Be sure and take your camera. You'll certainly want a picture or two. Have a wonderful time, and tell us all about it when you return!
