I heard this performed at Celtic Connections on the radio, but sadly can't find any tabs or chords for it. It's from his album Wheels and it really moved me and I would like to play it with my band.

I think there might be a capo on the third fret but other than that I'm rubbish at transcribing by ear.

Any help would be greatly appreciated.
Half Iago, half Fu Manchu, all bastard.
