Well bert, I'd be honored if you'd play it on the radio show tomorrow, but that wasn't why I brought it up.
Actually, I purposely tried to write a song that fit an old English melody and chord progression - and one that used the Battle of Culloden as a back drop. I also wanted to put a diferent twist on the theme, that being one that uses history (and geography) only as a backdrop, but told the tale of two lovers saying "OK, battle's over, we lost, but who cares, let's just get back into each other's arms and get on with our life/love!" I found an old folk song with a similar theme, and used some of its imagery.
Anyway - I hope you like the song, (by the way, it was written for a four part vocal on the chorus) ... and I suspect you'll agree that it fits your criteria for original "folk" songs.
