Gah! I can't find the tab. Broken Spoke Shuffle is A LOT like Cotton Fields, and remember that it was a demo. It starts off with the A-chord (in the shape of an F) at the fifth position. So it's the fifth string open and the fifth fret of the first string (High E). Then it goes up to G (in the shape of an F), and then for the last part of the intro it's A-E. The rest is mostly dancing around in the pentatonic scale. I don't hear the chimey Rickenbacker, so it's likely he's using his Les Paul. Glory Be is definitely the Rick.
This might give you an idea...
