Mike was just about the nicest man I have ever met. He was gentle, and funny, and patient with all of us at the workshop. He was generous with both his time and his talent, something I have always tried to be ever since. I'm not always as successful in that as I would like to be, but I surely have a great example to keep inspiring me. I have never had the pleasure of meeting his more famous brother, Pete. There are a lot of accounts on the internet about Pete's famous temper, notably when he wanted to take an axe to the power cord (probably apocryphal) when Dylan first played electric guitar at a big ol' folk music concert because he thought the music was too damned loud. I can't imagine Mike doing anything other than going along with the flow.
The guy playing the saw was very, very good, and if he didn't have perfect pitch, I sure couldn't tell. I have no idea whether or not he is generous with his time, but he seemed a gentle souls when Keillor interviewed him a bit after he played. I know that because of him I'm thinking once again of one of the purely nicest human beings I have ever met, and I'm grateful to him for that, if nothing else.
