I've been puzzling over the Ford tune as rendered in the sound file above -I assume something went wrong with the fingering of the last line which wanders away in the middle. I must go look at the book.
Now I get it, the tune is the one used for the bothy ballad 'Sleepytoon' - 'It happened at last Michelmas ah tir-ed o ma place, an ah went down tae Inch tae fee, ma fortune for to face'. It so happens I kept passing through Inch on a project in 2013.
I doubt the tune was made for that song though, I guess they reused tunes, and lines from some unidentified sung version of Van Diemen's Land keep juggling with the tune in my head. I have in fact found the tune used for the bothy ballad The Barnyards O Delgaty in a songbook, a song praising the good looks of Lowrie of Linton - Linton Lowrie.
