I love Woodies attitude and can't believe that someone who has influenced so many generations can become greedy and basically unhonest about the genuine authorship of a song. I think I learned the song in primary school in Ballacheulish, Argyle.
My advice to you DonMex is to sing the song, record it and rightly categorise it as traditional. Remember that, if the Foxes want to take up any court action it is going to cost them money and it's a case that they just can't win. I doubt if you will hear a word; after all, the Corries have done it.
Maybe we all should not forget the power of a huge international family like Mudcatters has as a pressure group.
Just one thing though; When the song mentions "over the borders" it's not Mexico that they are talking about!

ps I'll be involved in Cuillin FM, a local Skye radio station when it starts up aroung August/Sept. If you send a copy I'll certainly give it a load of blasts. PM me.
