I will be getting married in a very traditional Catholic Cathedral and they are very particular about the music. The songs sang cannot just be about love but about God's love, or God's presence in your relationship. My brother will be singing, he will definitely be singing The Prayer during the ceremony, but I was trying to come up with a song or two for him to sing while guests are being seated and up until I walk down the isle. The precessional and recessional will strictly be music from the paino/violinist. Any suggestions would be helpful! Thanks!
