An Addendum. I do not have the TTM text, so don't know its precise title. It appears that the correct title is "Dumbarton Drums", not "Dumbarton's Drums" as in Orpheus Caledonius and many later texts. "Dumbarton Drums" is the title of the song in a Scots MS of the 1740's, NLS MS 6299, and the title of the tune in A. Stuart's Music (for TTM), c 1726.

Here is an example of a song of which the traditional version is a much better song than the 'original'.
