The thick plottens, indeed! Thanks for the further information and please let us know if your wife finds out more information. I'd especially like to know the rest of the original tune to compare it with Stanron's reinvention.

Did you use an ABC converter for Stanron's version, like the Mandolin Tab - abcConverter I mentioned on 25 Nov 22 - 04:29 PM?

Also, when I hear the tune in my head, I hear it more as 6/8 time than 3/4 time.

South Africa. Not so far away from here, then. I'm in east coast Australia.
