Jonathan Edwards was one of the first harmonica players that made me want to learn to play, and then I discovered Norton Buffalo (all around 1978) and that did it.
I had the pleasure of seeing Jonathan Edwards live at a very small concert, probably less than 100 people... only him and a piano player. Awesome !
"Shanty" was definitely one of the most popular songs played by bar bands back in the late 70's and early 80's when my buddies and I were out and about.
