You're OK performing it WAV. Malcolm Douglas who was one of the greatest experts to grace Mudcat believed that it was probably American

"c.1860: 'Send Back My Barney to Me' written and published by Harry Clifton.

The song is quickly taken up by other performers in Britain and America. In the USA in particular it is 'favoured by Irish comedians' and is printed on broadsides and in songsters, frequently uncredited to Clifton and instead assumed to be, or claimed as, Irish.

By 1881 an adaptation or parody, with the tune a bit changed, begins to appear in print as 'My Bonnie'. It seems to have started out as a student song, most likely in America; a song-sheet issued in 1882 by Harms of New York as 'Bring Back My Bonnie to Me' credits it to H J Fulmer (Charles E Pratt) and J T Woods, but the text is reputedly rather different and no conclusions can be drawn without seeing both words and music. Evidently 'Barney' and 'Bonnie' continue alongside each other for a time, with other songs being written that appear to have been inspired by them; or at any rate by the former.

By the early C20, 'My Bonnie' has eclipsed its parent, which is largely forgotten. The song's enormous popularity leads to further parodies and to the tune being adopted for other songs in the same metre like 'My father was hung for sheep-stealing'. This leads even some scholars to assume that the tune is Scottish."
