The requestor specifically mentioned that he wanted a song sung by Gaberlunzie on their album "Rolling Home."

Allmusic.com lists this album. The full title is "Rolling Home: Live Frae the Briggs." Furthermore, it says the song is "1320," written by Gordon Menzies. I listened to a sound sample, and these were the words I heard:

"... of sovereign Scotland first took their solemn oath
For freedom we'll endeavor; for liberty we'll strive.
To England no surrender while one hundred true Scots survive."

That matches the lyrics Joe Offer posted above.

(Jim McLean: I would think you'd know, wouldn't you, whether Gaberlunzie had recorded your song?)
