Frank Zappa, possibly on his first album with the Mothers of Invention ("Freak Out"?) did a discordant barbershop quartet style song. From memory:

It can't happen here
No, no, it can't happen here
I'm telling you my dear
That it can't happen here

Who could imagine?
That they would freak out
in _________

(At this point, they'd repeat this line with different places; Kansas, Minnesota (maybe), Oklahoma

This is right up there with "Help I'm a Rock" and "Hungry Freaks, Daddy"
