Sounds like we're in fierce agreement!

I played a Civil War (CW) event out in VA last year, and one of the performers was called, The Banjo Doctor. He was a really fine player, and enjoyed doing the CW stuff up completely; dressed in correct costume, played only period instuments (at the festival) - so he had two lovely gut stringed, fretless banjos. We did a final set together, because of schedule changes and it went pretty well - but I had been asked to play a song that had a key change, and he was already tuned down two half steps - besides the chord progression had quite a bit of change to it (though the melody made it predicatable). I had played with him enough to know that he was a good musician and could at least stay "out of the way" during the odd bits - but the truth is he kept right up - key change be damned, on a fretless banjo!!! This guy knew his sh*t! He knew his theory.

I asked him after the show about his stage name, "The Banjo Doctor." I expected he'd been given the title because he was so good, or maybe because he fixed banjos or something. He told me he was called that because he was medical doctor! Ran a family practice clinic nearby! I was floored. This was one very fine, very well schooled musician - and a hell of a banjo. What was he doing wasting his time with that lousey day job!!
