I'll always recall a story a good friend of mine told me a few years ago. He was visiting New York in the late fities or early sixties and being a musician himself he was checking out the local scene. He said he was in a club one night when this guy came out in overalls, playing guitar and singing horribly. He recalls laughing at the tenacity of this guy for getting up in public in the first place. He then went on to say that on the drive back to Toronto, he couldn't get the songs out of his head. He was watching T.V. several months later and saw the same "Hayseed" on one of the big T.V. shows of the day and of course, it was Bob.
Thank God that those times allowed a person to say something if they had something to say. You didn't have to sound like Celine Dion to be popular.
