Crystal Gayle & Eddie Rabbitt - "You And I"

I'm not a gambling man, but I'd be willing to bet that many early-1980s wedding receptions featured newly-married couples dancing to Crystal Gayle & Eddie Rabbitt's "You And I".  I would also wager that Kool & the Gang's "Celebration" was also played since it would soon become the anthem of all wedding receptions (followed by "We Are Family", of course).
