well im gonna go with folsom prison blues, though i am also very fond of san quentin and the tale that comes with that song
I like the fact that most of his songs had stories to them. Not like nowadays where half the songs are about cheating on your girlfriend with your ex (hello hinder) Hmmm.....
I live near Folsom Prison. I think it showed up on America's Most Wanted briefly, but I didn't watch that much. Ring of Fire!
