Neither the song above nor "The Bonny Moorhen" in James Hogg's 'Jacobite Relics', I, #77, 1819 is the original erotic song of "The Bonny Moorhen", although both borrow a little from it. There's a traditional Irish version of it in Hugh Shields' 'Shamrock, Rose and Thistle'. Perhaps Murray on Saltspring could favour us with a better copy of the Scots original, which is probably of about 1765.
