"Urge For Going" is one of my go-to performance tunes. Kind of do the Joni version, but I've incorporated a few of the things Tom does. Both play in A major form capoed up, as do I (thanks to them). Love seeing Tom in concert; he's funny , engaging, and just a treat to see. I've learned 90% of what I know about open G tuning watching him , especially on Circle Game (with that business of doing B minor from the bottom string up with a partial (4 string) upside down barre on the 4th fret).
