Ceremony Music

(source)

As musicians, the music for our ceremony is very important to us. Perhaps because it is SO important, we haven't made too many decisions yet. We know that we would like to see friends of ours as the performers - just which friends still stands to be decided. I am pretty sure that David's groomsman Pat will be singing (I did let Pat know that I really wanted him to). In fact, I think it might be "Sunrise, Sunset" from Fiddler on the Roof, but not sure on that yet. Here are the semi-random music thoughts:

Prelude
"Sunrise, Sunset"
"One Hand, One Heart" from West Side Story (perhaps used for Unity Candle?)

Processional
Bridesmaids: Pachelbel's Canon in D
Bride: "Wedding Processional" from The Sound of Music

Ok, so that's as far as we've gotten! I would also like one of our friends who plays flute (know who, haven't asked) to play Ave Maria at some point.... can't decide if that should be during the prelude, or maybe the Unity Candle?
I would like one of my friends from high school to be the "main" singer - all of the ceremony parts, as well as any songs that someone else isn't singing. Again, haven't asked her.
Our biggest hangup is who to ask to play piano/organ. I really feel like the "Wedding Processional" needs to be on organ to sound right, but I only know one organ player. I need to find out if she is also comfortable on piano, or if we need a separate piano player. If separate, I can ask one of my fraternity sisters from BSU, but she doesn't live in town, so rehearsing with other people could be a problem.

I had hoped to have this cleared up before school started back up.... seeing as how I have to be there a week from today, I don't see that happening!
