The Occupy Wall Street protesters camped out in Lower Manhattan's Zuccotti Park are buzzing over a big secret musical guest scheduled to play this afternoon at around 4pm. We hear that it's Radiohead, who are in New York for a couple concerts.

It makes sense: Radiohead's lead singer Thom Yorke has a history of lefty anti-globalization protest. What do you think: Are the millionaires from Radiohead authentic enough to be the bards of revolution? They're certainly capable of mobilizing people: When their New York show sold out in minutes they almost caused a Twitter riot.

Update: It's been confirmed by Occupywallstreet.org the official website of Occupy Wall Street. An Occupy Wall Street spokesman told me, they have no permit but the police are "aware" of the event.

Update 2: Well! A Radiohead spokesman says the performance is not happening, though people on the ground still insist it is.
