Just days after Mick Jagger denied a report that The Rolling Stones are booked to play the Coachella festival in Indio, California in April comes a photo on the festival's Facebook page that might suggest otherwise. It is a picture of a round stone on a field -- a.k.a. a rolling stone -- with a caption that reads, "Happy New Years! We're excited, hope you are too!" However, the festival promoters, Goldenvoice, say it's a polo ball. In December, the Stones new app had a listing that they would be at Coachella, but it was quickly removed.
