I went to London with a friend to see him at (I think) the Victoria Palace and he was great. I know little of guitar proficiency and I expect his was a rather basic style...but effective! His voice was stunning and his delivery of songs was superb. He sang a version of 'North to Alaska' which I found absolutely compelling. Primarily a busker, I saw him playing for dimes around Quincy Market, Boston, Mass. where he was drawing big crowds. I seem to recall that fRoots did a feature on him but I may be wrong about that. Whatever, he died too young.
