I was at a friend's recently, and we were each trying our hand at a few Gary Davis songs. When I got towards the end of Twelve Sticks, he said "That's pretty cool - I don't know of that section". As I thought about it, I realized I hadn't heard it on any Gary Davis version either. I got it from you. It's the section where there is a D7 in a C7 shape with ring finger on the 5th fret 5th string, then it goes to a G chord in an F shape - then those two shapes slide up two frets to E7 and A respectively.
It's very nice, but now I'm curious if this is a Stefan improvisation, or is it something Gary taught you but didn't record? (or did I miss where he recorded it?)
