John Mayer was posing for the paparazzi in NYC yesterday before his concert in Holmdel, NJ that night. He was putting on quite the show. More impressive is that the gadget geek just updated his site with some cool new features like voting for the song you want to hear as an encore. Considering the positive feedback and news of a shirtless Mayer we're thinking we better buy some tickets fast. Now if only his site had a spot requesting for an Aniston appearance.
