Nice to see you posting to this thread before 2 in the morning, Ron.
I'm very impressed with your ability to sing complex music. I only read music at gun point. Actually, I'm getting a little bit better, over the years. I just was never motivated, because the music I want to sing doesn't exist in sheet music.

Many years ago, I did a version of Cryderville Jail. I say "a version" because I learned it directly out of the Folk Music Of North America Lomax book. The first time Dave Van Ronk heard me do it, he really liked it. He asked where I'd learned it because he'd never heard anyone sing it the way that I did. I told him that I learned it out of the Lomax book. He said, it doesn't anything like that the way it's written down by Lomax. That's one of the little known benefits of not being able to read sheet music very well. You can discover totally original variations in the commonest of song books :-)
