So nice to hear that Doc is still working his magic. He's a national treasure. I've never seen him in person, but I did get to see and photograph a Bill Monroe show about 25 years ago. At least until his people ran all the photographers off. He was a tough old guy.
Great image of Doc, Tina. You present him exactly as he "sees" himself -- just Doc pickin, clear and light. You should let him know you have this image. It is perfect.
