Did any of you attend the World's Fair in Knoxville in the 80's? I was so impressed with the performances of what I supposed were the "cream of the crop" of the Bluegrass Music World. I had never been a fan of Bluegrass, and knew nothing about it, but I was overwhelmed by the performers who gave us a poignant and memorable history lesson on the music that originated in the hills and valleys of our ancestors. I was amazed at the things some of the groups used for instruments; washtubs, washboards, jugs, etc. I tried all these as a kid, but my efforts didn't sound like theirs! Also, some of the performers were in their 80's and 90's. It was a wonderful experience...Gloria D.
