I think the tune of Katey Bairdie was a pipe tune before the words we know today were written in the 1840s. I remember this song when all my friends grew up with the singing kettle, and because we play this song as part of our polka set the folks know this song and like it a lot. The tune was an instrumental before the words were added, but lots of kids think that when they hear it they are hearing London Bridge is falling down, and don't know the Scottish tune or words (but many now have the singing kettle).
