Love and marriage
I think this is too trivial to be included in the trivia section, but still fun enough to mention.
In Damned United, Michael Sheen sings Love and Marriage while celebrating the Second Division title with Derby players.
In Frost/Nixon's birthday scene, the singer is performing Love and Marriage with words adjusted to Frost and Nixon.
In Masters of Sex episode Love and Marriage, Rose McIver sings Love and Marriage.
(I guess it doesn't mean much, just that it was a popular song...)
