Alright, I'll bite.
Since it's been reported just about EVERYWHERE else we'll go ahead and run it here too. The Arcade Fire headlined Jazzfest this year and since EVERYONE is a fan of Cyndi Lauper (no really, she rules) they decided it would be a good idea (it was) to bring her up on stage to cover her uber hit, Girls Just Wanna Have Fun, with them.
So yea. That happened. Good thing I skipped Jazzfest this year, right?
