Music

My wedding is in June of 2004. I feel lost and don`t know where to start with the music for the ceremony. I want some unique songs. I have a female and male singers. Does anybody know any good songs that would blow people breath away.
Me and my fianca come from very different families but yet we are a lot alike. Nobody thought our relatiionship would last. I need a song that is going to say something how strong our love is. ??
