Help please!!

I've two friends getting married in May, one is from Uist and she wants a suitable Scots/Gaelic song played as she goes up the aisle!

Unfortunately, all that she's found so far are the mournful, sad songs about losing a love, being parted by sea etc. etc. Alternatively, she has come across some lilting jig types which, although cheerful, she can't imagine skipping up to the altar!!! It'll be on a tape or cd so no need for sheet music or tabs etc. And there's also no need of literal translation as long as she knows the story of the song.

Any help would be appreciated as the wedding is fairly soon.

Many thanks, best wishes, Yvonne
