The Hives and Cyndi Lauper: A Christmas Duel
Yes, the 2008 release date makes this post a rule-breaker. But it was a single, and too explicit to play on the radio; it got no reception whatsoever, as far as I can tell, and thus, it meets the general spirit of obscurity here - i.e., most folks have never heard it. As such, in the spirit of the season, and of punk in general, I'm sharing anyway, just this once.
And you just gotta hear this one. Because how's this for holiday cheer: a drunken punk rocker duet which cites both sincere death threats and sexual encounters with two generations of in-laws, and - though it starts as a raggedly tender ballad - goes on to combine a crashing parody of the Phil Spector-era holiday popsingle sound and language rich enough to need a warning label. The narrative premise is, essentially, that Christmas offers forgiveness, or at least, that the snow and celebration drown out the filth for a while. It's like a Sid and Nancy Christmas special, albeit more melodic.
