Not to contradict Mr. Hearl's knowledge of the background of bluegrass music, but being from KY, I always thought bluegrass music got it's start in the bluegrass state of Kentucky, with Bill Monroe being the father of bluegrass music and performing years ago at Renfro Valley, Mount Vernon, Ky. Many of our KY country music singers got their starts at Renfro Valley. I remember Renfro Valley Barn Dance from childhood. That would be 1930s, 40s (hated to have to say that)! My father-in-law sang there with a quartet in the 1940s. Renfro Valley is still a big attraction on Saturday nights. If any of you are familiar with "Carl Hurley", he will be appearing there about April 24. He calls himself the lecturing professor, and is from East Bernstadt, KY. He is very funny.
