I know this is years too late, but since it's relevant to the original question, it's worth passing on for anyone who may have a similar need and is checking this thread:

Take a look at The Delting Bridal March, which is in James Hunter's The Fiddle Music Of Scotland. In a note at the back, he writes, "Delting is the district on mainland Shetland between Olna Firth and Dales Voe. It was long the custom at weddings in Shetland for fiddlers to lead the bridal party to and from the church."

It's a 6/8 march, so it has a lovely swingy rhythm, and - as befits a joyful occasion - is in a major key.

I'm sorry I can't help with Laurie's request, but someone undoubtedly will sooner or later, and this at least pushes it back to the top!
