I first heard the song in Inverness as Hush, Hush - and looked for it a long time under that title without finding it same as you!
There are so many alternate titles to so many tunes! I used to get tons of mail asking for a tune that was already on my pages - so I put the search engine up. It's pretty slow because there's so much to go through (I'd like to find one that would be speedy, cheap and not add a lot of extra storage space... every webmaster in the world in laughing..) It will find stuff by phrase - sort of a poor person's mudcat type of search. A lot of people start there because they don't like the background music!
Of course the search engine isn't perfect either. There are several ways to spell bonnie, etc, etc, etc... Just look at all the trouble we have at the cat! I sometimes still can't figure out why something doesn't show up when it's there all the time!
