Rather than dig up a three and a half year old thread, I'd thought I'd start a new one. The original thread was about what key 'Folsom Prison Blues' was in'.
The general consensus was 'whatever you can sing it in'. Well, I did a little youtubing tonight. And the man himself, I observed him playing and singing in no less than three different keys. F, E and G. I guess it just depended on how his voice was at the moment. I saw more videos of E than F, and one in G.
Just for shits and giggles, I dug out a capo that I knew I had somewhere. Clamped it on the first fret and went to town, shot a man, just to watch him die.
I think that's the first time I ever actually used a capo, in a song.
