I agree with many of the names so far, especially what you mentioned Art. One aspect of this is the unsung (pardon the pun) hero. This is the person you first heard who turned you on to folk music. Maybe it was one of the greats already mentioned or maybe it was a singer in a folk bar. Perhaps it was a music teacher who loved folk music and played it for their class. Maybe a song leader at camp. This would be each of ours most significant and thank the Lord they came around when they did. Dan
