Lee DeWyze Performs 'That's Life' on 'American Idol'

When Frank Sinatra sang "That's Life," the song became a masterpiece, a devil-may-care case study in the art of cool, careless crooning about enduring the bad days.

On Tuesday night (May 4), Lee Dewyze made the song his own, simultaneously conquering his own demons and the specter of the Chairman of the Board.

The spiky-haired "American Idol" dark horse took on a signature tune from Ol' Blue Eyes for the show, with necktie appropriately undone. Accompanied on a Hammond organ by mentor Harry Connick Jr., Dewyze straddled the top of the instrument as if paying tribute to the bar-embracing persona of Sinatra, backed by a bluesy band.
