Hi all! This is my first post here, so be nice. ;)

I've been trying to work this one out on guitar recently, with a couple of friends, listening to the Albion Country Band version, with Shirley Collins singing.

As far as the theory goes, my far more knowledgeable friends have told me the melody is in C Pentatonic, while the harmony is C Dorian.

It's in 3/4 time, around 107 BPM, capo on the third fret if you want to play along with the record, (you can play the open chord version too, but it's not so easy, drop all chords 3 semi-tones).

Intro
Am G C/D Am

Verse (four sections, four bars each, one for each line)
G C D Am
Am D G Am
Am D G Am
G C D Am

Break
G CD Am

I hope that was somewhat helpful to some! What an amazing but very sad song, with a melody to die for. ;)
