Last night, John Mayer announced via Twitter that he was playing a secret concert at the Village Underground at 3 am for only 10 dollars. But the surprises didn't stop there! After his concert, he stopped and sang "Billie Jean" with a fan outside the bar.-
Warning: It's sort of a lot of falsetto.
Disclaimer: We have no particular reason to believe this man is homeless--that's just what the youtube page said, so we're going with it.
Moral Of The Story: You never know what you might see on a 5 am stroll in New York City.
