John McDermott sings the words posted by Malcolm (and slightly adapted from Hyslop, 1821) to the familiar "Scotland the Brave" tune - under the title "Scotland Forever":

And Ewan, always when I say tunes are "close variants" or "about the same," I mean that the average quasi-musical person like myself recognizes them as very much the same. When I say they're "different," I mean that it takes quite a perceptive listener to discover a real resemblance.

Joe asked on another thread whether "Do Me Ama" and "Yarmouth Town" are "the same song." I think that question comes from overexposure to the early ballad scholars' desire to find traditional "links" and then lump songs together as being the "same," even if the textual and melodic differences are obvious.

I think the tunes of "Scotland the Brave" and Corrigan's "Irishman's Toast" are "about the same." The usual tune of "O'Donnell Abu" bears only a slight *melodic* resemblance, and melodies are what I'm talking about. "Hail to the Chief" bears none. "The Bloody Fields of Flanders" bears none except perhaps somewhat in the opening bars. To my way of thinking, that means that like "Hail to the Chief," it's a different tune by any ordinary standards.

The latter tunes differ even more than do the words of "Yarmouth Town" and "Do Me Ama." They're unmistakable.
