Brigid,

I don't know how they do the "blue clicky" thing, but here's at least a link you can type in your browser's address bar to a site where you can download a midi version of the song. The lyrics are there as well.

When you opened this thread, you used the word "beautiful" to describe the song you had in mind. I'm not sure if I'd call "Nutbrown Maiden" beautiful, and that makes me a little unsure that it is indeed the song you are hunting for. It is a pleasant, catchy tune though, but it's distinctly Scottish (if there is such a thing, from a musical perspective.)
