I dislike Jazz. I just tolerate blues (don't blame me it's just how I am). He has altered my attitude to both. He played Jazz , Blues , Traditional and Modern all on the same guitar , no sound system or microphone. He drifted in and out of Delta blues and 1930's Jazz with a voice ranging from industrial to silk.
He talked of his childhood and influences. Played songs to emphasize his life. He played with the gusto of a 20 year old and the quiet competance of a lifelong musician.
HE TALKED TO THE AUDIENCE!!!. All the time. Chatting and swapping memories with songs interspersed with quiet jokes and laughter.
Dave, welcome to the world of folk club performers who began in the 60's.You sound so surprised! John isn't a legend "in the making", he's been a legend for years and years. Glad you've discovered him and are spreading the word.
