In the early 60's I was going to UBC and was into the folk-music scene somewhat. I frequented a place called "The Ark" In Vancouver, among other coffee houses. There was no booze and the college crowd was enthralled by singers of all races and places. My favourite singer was Don Crawford who had a raspy voice and played one incredible 12 string guitar. Vancouver fan's loved him but he never caught on as the hit artist I knew he could have been. I remember that he sang "Dont think twice its all right" better than anyone I have heard including Bob Dylan and Peter Paul and Mary. He had a cute rendition of a song I have heard that had the line, "There's is in a little house/ There's is in a pear tree, full of pearses...they don't have no worries or carses". I had an LP of his but it was full of songs I never heard him sing live and was disappointed in it. No hits for him on Napster. He is mentioned on this website, as a singer at the Jabberwock http://www.chickenonaunicycle.com/Jabberwock%20History.htm
My email is jimwbruce@gmail.com, if you want to correspond. I would love to find out what happened to him. I know he tried acting but apparently was a colour neither very black or white, and the story was that Hollywood had difficulty placing such folks back then.
