NYDailyNewsPaul McCartney will sub for Kurt Cobain as Nirvana reunites for Wednesday night’s special Hurricane Sandy relief concert at Madison Square Garden. Nirvana’s Dave Grohl asked McCartney to join him and Krist Novoselic on stage for the special 12-12-12 event, according to The Sun. “I didn’t really know who they were,” the 70-year-old Beatles legend told The Sun. “They are saying how good it is to be back together. I said, ‘Whoa? You guys haven’t played together for all that time? And somebody whispered to me, ‘That’s Nirvana. You’re Kurt.’ I couldn’t believe it.”

If you like music and not just whomp whomp-ing or bragging about all of the gold on your chain (not hating, I love both of those things), then you should be excited to see this go down. Only if Sir Paul is serious about doing Nirvana, though. Doesn’t mean anything if the old guy gets up there and starts Love Me Do-ing and fucks up the whole vibe. But if by tonight Paul McCartney is screaming Smells Like Teen Spirit, well boys & girls, we would have just witnessed greatness.

The Definitive Top 3 Band Subs We Need To See Before The Apocalypse:

3 – Radiohead fronted by Frank Ocean

Frank Ocean is just one of several R&B singers to cover Radiohead using a distinctly non-Thom Yorke singing style, and it’s almost always worked. Could get weird, but then again weird is good.

2 – The Black Keys fronted by Bruce Springsteen

You either love Bruce or you hate Bruce. Either way, this combination would be perfect if for no other reason than to see middle aged Jersey moms fight for space in the crowd with skinny-jean’d hipsters and uppity music snobs. “Keep playing, Bruce! You’ve only been on for 3 hours!”

1 – The Jimi Hendrix Experience fronted by Andre 3000

Yeah, Andre isn’t in Jimi’s league when it comes to guitar ability. Frankly he’s probably barely ahead of Lil Wayne on the guitar. It wouldn’t matter. Those two guys are the same guy, so much so that Dre was to play Jimi in a movie until they couldn’t get the music rights and the whole thing got Jackie Jormp Jomp‘d. Have someone Milli Vanilli the guitar solos and make it happen.
