I was very impressed with John Dowling as a teacher and as a banjo player. He sorted out Frank's problems (except the stage fright) very quickly. I've seen him at a few festivals over the last few years, he's made an impact at Sore Fingers Summer School (near Stow On The Wold) and he'll be teaching beginner's bluegrass banjo there in a week's time, so catter's can try him out!
