'The Beatles: Rock Band' Rooftop Shindig Featuring McLovin

As a means of capping off Microsoft's press event, Harmonix threw a rager for "The Beatles: Rock Band" on the roof of The Standard Hotel in downtown LA, allowing folks of all creeds to come up and try their luck at being one of the fab four.

The featured player of the night, the one, the only, McLovin.

McLovin!
