Oh, don't worry about me, M.Ted. I am playing the song, with chords that sound tolerable to me: finding the best of all possible arrangements is not currently one of my goals. I started this thread out of curiousity, since the chord name didn't seem to jive with what I know of theory.
Before talking to you, I was playing it B7sus4 (second fret on the A, D, and G strings, all other strings open). Now I'm trying it as Bm7 - Bm7/E (adding the open low E string in the second half of the bar).
Thanks for working on this, and I'm very impressed with your dedication to figuring such things out, and sharing your knowledge with people like me. What I've read in this thread has changed the way I play this particular song, and has opened a new door on how I think about chords.
And I'm having fun with the song. I love the bit about "no deeds to do, no promises to keep." It reminds me of one of my favourite poems: "The woods are lovely, dark, and deep, but I have promises to keep, and miles to go before I sleep..." Equal and opposite feelings that are both very true to experience.
