What a beautiful song! Took me some work, perfect to be posted on May 1, Labor Day.
D. I think. Sounds like home to me.
Wonderful chromatic descending bass in the verse and the interludes.
I did not transcribe all the improvised interludes, so use the chord pattern of the intro (A)
to make your own instrumental breaks. (B) is the verse and (C) is the chorus.
Originally, the first chord of the chorus is a G over B, but I prefer a plain open string G chord here.
