This one was just a loose jam and was much longer than it appears here due to file upload size. It was faded in just about where the bass starts to go through the I-IV-V changes; before that it was a continuous I 'holding pattern.'
The acoustic slide was done on a 1942 Martin dread with a Dunlop steel slide.
Naw, just kidding - the guitar's a Johnson 620.
It was basically a one take thing for fun. Hope you enjoy!
