Hi, Chanteyman - there's a message above from Sandy Paton (click), the late owner of Folk-Legacy Records. Sandy says that Dalglish, Larsen & Sutherland learned the song from Dillon Bustin, who made up at least part of the song.
I'm hoping Dillon will respond to your Facebook message or mine and give us definitive information.

Here's the URL for Dillon Bustin's Website:

There's contact information there.
