To brdalton-Many thanks! I've tried transposing your chords to B and playing along with the record--you are very close. a whole lot closer than I was!--but he is doing something a little different. Still your arrangement is a tremendous improvement over mine, so thank you. This song is wonderful, but it has been driving me nuts and I truly appreciate your help. PS--Hammond certainly loved using diminished chords (Trucker's nightmare for example). I wonder, given your experience of him in concert, if he also slack-keyed his guitar?
