I've got a copy of the aforementioned 1862 volume "Songs Of Scotland Prior To Burns" edited by Robert Chambers. In the preface to the song he states

"In Herd's Collection is a long rambling dialogue song of not much merit, but sustained by a melody of uncommon beauty, and for a Scotch sentimental air, animation. After the song had in great measure been laid aside, the air retained popularity, and in later years has been insured a sort of immortality by being adapted as a melody for Burns' charming song, A Rose Bud By Early Walk. The present editor, unwilling to see the original rustic song entirely perish, has condensed and purified it so as to fit modern society"

He then gives his version of the lyric. Reading from that it certainly seems that if Burns wrote a version it must have been obscure or at least Chambers gives no hint of knowing about it.
