i've seen him many times
best though was at a bluegrass festival . after his afternoon performance , he gave a seminar on 'pickin'
someone there asked him about playing jazz , well he started improvising and playing old jazz tunes ....
after the evening concerts , the campfire picking started .
it was a pleasure to see him out with the 'masses' just jammin'
one of the best times we had at a festival ....
