Late Night With Conan O'Brien returned to the airwaves last night, bearing fresh episodes and a spectacular Writers Guild of America supporting beard. What has the staff of Late Night been doing in its down time? Playing Rock Band, like the rest of us lucky Westerners.

Stick around for the Beastie Boys/All In The Family mash up.
