In G that would be D7. Except the book I used has a C chord there ("sometimes"). On the banjo in G tuning, D7 has two notes in common with A minor and C has three, so that's why it works well. (The pivotal note in the chords is C... on the first fret of the second string in a C, D7 or A minor chord.) I'm not trying to sound like the Cashes since I haven't heard them do this song. On the "tremble" I am going between open G and A minor.
