This post is much easier than many of the others in this challenge. One song that I have wanted to be played as the processional at my wedding is "Let Me Call You Sweetheart." It's a very old song, but the lyrics are amazing.
I must admit, the first time I heard it was while watching "Anne of Green Gables" and being the helpless romantic that I am, I could not resist loving the song. (Now I want to watch all of the movies again!)
