I'm glad you liked it Bob. I've seen Mark perform live umpteen times, but the best for me was when I actually got to meet him. I had just gotten my custom Martin guitar a month or two before and Mark was doing a meet and greet at the Merle Watson Festival. I handed him my guitar and told him it was brand new and asked if he would break it in for me and show me how it was supposed to be played.
He spent the next 15 or so minutes burning the strings off of it and then smiled and handed it back to me and simply said "Nice guitar".
I did get him to autograph my case and it's sitting next to my desk as I type.
