Dear Angun,I know that I've heard a version sung in Scots-Gaelic -- I believe that Alisdair Fraser (sp?) does one. I know that there are supposedly several verses to the song, but the only one I've ever seen is the fourth verse I have on my webpage.
I hope that Philippa sees this thread, because she probably knows where to find the verses if they can be found.
