Well, if it's Borders, it might be something linked with my lot - one of my great-something-or-anothers was Mungo Park, a once famous explorer from Selkirk.

Whether the song refers to him or not, it tells us that Mungo was a name in use in the Borders area in the 18th century.

btw, if there is an outside chance that this fiddle tune was composed in honour of my ancestor, I'd love to hear it :-)
