While performing a surprise concert with Jack White in Nashville last night, Conan O'Brien announced his plan to release a vinyl album of rockabilly hits. The 300 fans who packed into White's Third Man Records heard a sneak peak of the recording, which will include covers of Eddie Cochran's "Twenty Flight Rock," Elvis Presley's "Blue Moon," The Stray Cats' "Rock This Town" and Radiohead's "Creep." A fan in the audience posted video from the night here. [Yahoo!]
