The Johnny Cash Project is so cool. I recommend starting at this link to get an idea of what's going on with the site. It's a great site, and I really appreciate the work they have put into it. Here's the Man in Black himself performing the same song I covered but doing an infinitely better job of it in 1994 at The Viper Room in Los Angeles. Here's Drive On.
I would have put a video or pictures from the site up, but I couldn't find a way to embed them, and I think they want it that way. For something so cool, I can respect it.
