Processional/Recesional Music

Just started thinking of what music to use.

What did you use or are you going to use for:

BP walking down th aisle?
Bride walking down the aisle?
Bride and groom leaving??

For the processional we'll be using string quartet instrumentals from tribute albums:

Parents: Thank You by Led Zeppelin
BP: Say Yes by Elliott Smith
Bride: Maybe I'm Amazed by Paul McCartney

For the recessional we'll be doing The Best Is Yet to Come by Tony Bennett

BP Walking down: The Prayer, Andrea Bocelli

Bride: All I Ask of You, Phantom of the Opera

Recessional: Bittersweet Symphony by the Verve
