According to the words and music I have from Broadside #87, the chords are as follows:

Verse:

//:Dm / Gm / C / Dm / - / Gm/C/Dm/-/Gm/C/Dm/-/Bflat/C/Dm/-://

Chorus:

/F/Am/Dm/-/F/A7sus4/Dm/-/Gm/C/Dm/-/Bflat/C/Dm/-/-/-/

For anyone unfamiliar with the above form of chord layout:

//: ....:// is a repeat

/-/ is another bar of the preceding chord

The tune is anacrusic (ie it starts on the third beat of the bar, so the first Gm is played as you sing "walk".

Hope this helps - it does work.
