concerened -- not sure which version you want the chords for, the Carthy/Swarbrick to the Drunken Piper/Collier tune (which they did do accompanied), or the Bellamy/YT one [which they sang unaccompd]? But both are fairly simple tunes for which you should be able to find the chords for yourself just by strumming and changing the 3 basic chords, tonic, sub-dominant, dominant, till it sounds right. Not a difficult thing after a bit of practice with pretty well any tune which doesn't modulate minor/major.

Good luck.
