I'm looking for a vocal classical piece performed during the trailer of "The Nativity". You can view the trailer here (http://www.movie-list.com/trailers.php?id=nativitystory)... the trailer you need to look at is the quicktime trailer. I'd appreciate any help... I had never heard the music before but it is so beautiful! I saw this trailer before Pirates 2, and also heard it was shown before Superman Returns as well... Thanks all!
