The DT file was taken from a book. The song is reasonably well known; Ford printed it in his Vagabond Songs, and there are versions from oral currency in the Greig-Duncan collection; 'Jock Tamson's Bairns' recorded an arrangement of the Ford set back in 1980, and probably a lot of people nowadays know it from that. It appeared on broadsides of the later 19th century, examples of which can be seen at both Bodleian Library Broadside Ballads and The Word on the Street (National Library of Scotland).
