We're still processing the incredibly weird news that Wings frontman Paul McCartney will be joining the surviving members of Nirvana (Dave Grohl, Krist Novoselic, and Pat Smear) to perform tonight at the massive Hurricane Sandy 12-12-12 benefit concert at MSG. Considering that Paul is already dead, this seemed like a really odd way to resurrect him. While the supergroup will definitely play a new song, it's unclear whether they'll let Macca try his hand at "Territorial Pissings." That hasn't stopped Twitter from imagining a world in which Nirvana and Beatles songs don't just share the same DNA in their chords.
