Overview: Superstars Kelly Clarkson, John Legend, Jennifer Nettles and Robin Thicke, take the stage with their remaining Duet partners for an evening of standards from the Golden Age of music. America's voting results from the prior week will be revealed at the top of the show, sending one contestant home, so that only four remain in the competition to perform that night. At the end of the night, the polls will open once again and America will get to choose who stays in the competition and who is eliminated.
