Looking for the name of a song, and perhaps a group or choir that sings it...

OK, I have watched the movie A Walk To Remember, and towards the beginning, there is a church scene, and the choir sings a song, it goes something along the lines of - ’let the light from the lighthouse, let it shine on me’

Does anyone know the name or a choir who sings it?  I like the song alot, and want to get a copy to listen to any time I would like.
