piano music as a prelude to marriage and the wedding?

I play the piano for a wedding and need the music for the prelude. In addition, the bride said he has not decided on a piece for the procession and asked for suggestions. So what parts are good for a fairly traditional prelude procession. Links to scores (Preferably free: P) would be good. For the prelude, I play a set of over Nice Rainbow, and parts of Yiruma. (To give you an idea) procession The bride is Variations on Canon by George Winston. And a traditional wedding in March for the fall.

There are not many good links out there for free classical sheet music (believe me, I tried!). But I recommend going to the music store and ask for their opinion. If you do not do what you need on hand, order it in. Someone may have an experience with suggestions for marriage and what is commonly played. I know that Pachelbel's Canon in D is often played at weddings is for the woman or the wedding. As for my own suggestions: Definitely would not go with the other suggestion of Moonlight Sonata because it is beautiful but a bit depressing. Air on the G String (Bach) is beautiful and often played at weddings. Prelude in C major (Bach) Jesu, Joy of Man's Desiring (Bach)
