No list of mother-son wedding songs would be complete without this perennial favorite from the Broadway musical and 1971 film adaptation "Fiddler on the Roof." It's about the passage of time, changes and -- well, life. You don't have to be into show tunes to recognize the appropriateness of choosing this song for one of the parent dances. If you think it's a little too overused, look at it this way: Weddings celebrate tradition, and there's nothing more traditional when folks get married than taking a moment to pause and reflect on the meaning of life. There won't be a dry eye in the house.
