As I get older, pieces of favorite music from my past become new and greater from a few moments in the movies. This song was beautifully used in the final credits of "Love Actually" as photos taken in the reception area of Heathrow airport are shown, ordinary people greeting loved ones and long lost friends. As we watch these interactions, The Beach Boys sing, "God only knows what I'd be without you . . ."  These people's happiness and tears, I think, become ours as we watch and remember.
