I've just gone through my "Corries Complete" book. It styles itself "62 of their favourite songs from Scotland". This suggests that they probably had others too. As you can probably guess, it's not in the book . I looked at the words of all the songs just in case. I also looked on an Lp I'd got, without luck, but somewhere I should have a cassette I could try. If I get any joy I will let you know.
