After a much-publicized departure from hosting NBC's Tonight Show - and the severing of a 22-year relationship with the network - O'Brien hit the road with a 32-city music-and-comedy show to exercise his performing chops and exorcise a few demons. The "Legally Prohibited From Being Funny on Television Tour" was O'Brien's answer to a contractual stipulation that banned his appearance on television, radio and the Internet for six months following his last show. At times angry, mostly hilarious, O'Brien works out his feelings about the very-public separation with comedy and rockabilly music, engaging in bits with on-stage guests such as Stephen Colbert, Jon Stewart and Jim Carrey, duetting with Jack White and sweating out manic Elvis Presley covers with his band and back-up singers.
