Jack White is many things, but predictable is not one of them. For the b-side to his latest Lazaretto single, "That Black Bat Licorice," the Third Man honcho covered a song by Harry Connick Jr.

It's safe to say no one saw that coming. Maybe Jack's been watching a lot of American Idol lately?

The song, "Blue Light, Red Light (Someone's There)," is co-written by Connick Jr. and hails from his multi-platinum 1991 album Blue Light, Red Light.

Harry Connick Jr. Says Reinvented 'Idol' Has 'Ridiculous Amount of Talent'

White's recording borrows heavily from the '90s Big Band revival -- if you took out White's voice and replaced it with Brian Setzer's, no one would blink.
