Very nice John!
On a trivia note, I also listened to Midnight Special. In downtown Shreveport, near where I live, there is a statue of the local man who wrote it, Hudie Ledbetter. He is better known as Leadbelly.
He was pretty much a rascal, and spent his share of time in jail, but wrote some great songs such as this one and Goodnight Irene.
Thanks for sharing your talent!
