Did some research this morning. (Translation: I noodled around on the guitar until it sounded right)
Not too suprisingly it is a 3-chord song. Since I was nice (read: foolish) and lent the CD to my fiddler last week, I'm going strictly from memory, and I know there's more complicated stuff that they throw in, but the skeleton of the song is like so:

HARE OF KILGRAIN

(C)Come all you bold huntsmen of honor and fame
That (F) weekly appear on the (G)braes of Kilgrain
With (C) servants and horses and dogs at command
(F)Young Richard hunter for to (G) lead on the band

I know there's more you can do with it but that's the basics. Now it's up to Old Brown's wee Lassie to enter the lyrics... and if you're still in touch with Casey, tell him to re-release Pawprints. It's too good an album not to have, and my copy is so played, it no longer playable.
