The story of the song is pretty interesting. It seems elusive since no one seems to know or have heard of it other than Jen.
I keep meaning to check my Burns collections (he had some masonic connections) but I don't honestly expect to find anything - I'm sure I would be aware of it.
Roslyn Castle and the chapel are surrounded by mystery and anything that may help to unravel the threads of history is always welcome.
One thought though; is Jen pulling our legs?
Jen, you need to give more information. I'm not about to embark on a wild goose chase.
