I only discovered him a few years ago during a 50s/60s folk music period I was immersed in. Love his voice and his message. He has a neat website too. His body is gone but his soul and voice are with us always.
Saw him a couple of years ago in a small club in Cambridge, MA. What an incredible stage presence and energy. He broke a string on his Guild and switched to another one with out missing a beat. A very special musician. He will be greatly missed.
