Ok, now this may sound a bit ridiculous, but have a listen to High School Musical 3's 'Can i have this dance'. When I was watching the movie with my dd's, i heard the song and thought it would make a great Bridal waltz. You can see it on youtube.

I walked down the aisle to Savage Garden - is it Truly ,Madly ,Deeply ?? and danced to Lady in Red - (even though i was wearing white.)
Hope you find something you like
