I have some master tapes from the "Tucson Kitchen Musician's Association" in U-Matic format. They are from the 2nd year of it's operation, which is now known as the "Tucson Folk Festival". If anyone knows who this artist is, please let me know in the comments. I'm playing along with a 50 year old tape on a Mellophone. (York Band Instrument Co., Grand Rapids, Michegan.)
