Well if I was getting married again I would want Anne Mattila's "Maijan ja Jannen häävalssi" from the CD "Unihiekkaa" (2004). It means "Mary and John's Wedding Waltz", and the Finnish words mean something like "I love, love, love you: do you, do you, do you believe me?" but the tune is the most mournful waltz I have ever heard. But perhaps I have been to Finland too many times. Ariman (www.ariman.fi) have a copy - I've just looked.
