What music are you using to walk down the aisle, and is if different than you BPs music?

I'm using Cannon in D (we've got a violin trio, sound it should sound great in the church)...

Do the Bridal party usually walk down to just 'prelude' music?

I'm contemplating having them walk down to the beginning of Cannon in D because it's a long a beautiful song, and if I walk down to it only, you won't get a good just of the song (Infant Jesus isn't that large of a church).

I'm going to call the music coordinator at the church and see what she recommends, but I'm curious to hear what everyone else is doing.
