This song can be found in The Jacobite Relics of Scotland, Second Series, collected by James Hogg (Edinburgh: William Blackwood et al., 1721), page 97.

It has notation for a tune there as well. It doesn't identify a chorus as such, unless there is something implied by the notation that I don't understand.

The title given there is THE ATHOL GATHERING.

Lyrics are identical to those posted by Mbo above, EXCEPT for the last verse, line 5, where it has "Bend the musket, point the rapier,"—which I assume is a mistake. Muskets don't bend, do they? Unless "bend" had a different meaning then.
