Okay, first off, forgive me if this is "old news" to you. I'd never seen it before today (though the video's been viewed over 8 million times!).

Andrea's dad definitely would have danced with his daughter at her wedding. Unfortunately, he passed away before he had the chance. The bride's brother Nick made a recording of himself singing "Butterfly Kisses" and had it played while he and a few other guests took turns dancing the Father/Daughter Dance with Andrea. I admit, watching this had me getting a bit teary-eyed.
