Interesting, this one.

It was originally published in Cromek's "Remains of Nithsdale & Galloway Song", being contributed by Allan Cunningham. Cunningham later included it in his own "Songs of Scotland".

Later still, Cunningham admitted to writing it (when pushed) along with a host of other forgeries (including "A Wet Sheet And A Flowing Sea" (which see the Mudcat Threads for).

There's some discussion of Cunningham's song forgeries in another thread on Mudcat.

Jacobite, it ain't (except in sentiment).
