Last weekend we saw Bela Fleck and Chick Corea in Moab Utah. Bela always comes out and signs autographs, talks, takes pictures, or whatever you want after the show. I mentioned something that Bela was the nicest "elite" level musician I know who always took care of fans. He laughed and stressed that that was after shows. Before shows he does not want to be bothered, approached, or have anything disrupt him as he prepares for the night... So you are not alone. Even the elite level musicians like Bela have the pre show routines and nerves.
