Jack Black and Boy George rocked out with the spirit of Jim Morrison Monday night on Conan with this memorable performance of "Hello, I Love You"...

Discussing his music influences on the TBS late-night show, George said he'd "never gotten past the '70s -- The Stones, The Beatles, The Doors, [David] Bowie." Conan seemed surprised that the Jim Morrison-fronted band was on his list. But before George had the chance to reply, Jack jumped into the conversation, claiming, "Jim Morrison had the best yell!"

That led to an offer for Jack and George to sing a Doors song. And conveniently enough, Doors guitarist Robby Krieger just happened to be with Jimmy Vivino's band.
