But Evil Me (okay, just Me) would be so, so amused if some school somewhere used Fun's song "We Are Young" as its prom theme.
Getting high, getting drunk, bar-hopping, bar-closing, carrying friends too drunk to walk... oh, that could be so, so awkward. Gloriously so. And maybe even at times awkwardly honest! Hey, I never went to a prom, but I've heard stories.
That epic awkwardness is what would happen if a school didn't play attention to the lyrics, or just heard the chorus "Tonight, we are young/ So let's set the world on fire, we can burn brighter, than the sun..." -- and wouldn't that work so well as a prom theme? BUT THEN THERE'S THE REST OF THE SONG.
I mean, Spinal Tap's "Tonight I'm Gonna Rock You Tonight" would still be a worse choice, but not by much. (Oh. But that'd never get past the Grammar Police. Never mind.)
