Format
Not including pilot episodes: Seven celebrity artists choose a non-celebrity partner from a selection of people who submit performances to perform a duet of their choice. Each pair is given exactly 4 minutes to perform and earn votes from the 500 live voters in the audience and the celebrity panel. The order is selected by the current first place duo, and with the exception of the pilot episodes, the winner of the previous episode chooses the first performance. The voting results are shown directly on the screen behind the performers, and at the end of all the performances, the duo with the highest vote count is the winner for the episode. The winners are invited back to the show for the next episode, and another duo is chosen for "The Duet You Want To See Again" by the audience to be revived for the next episode as well.Panel of celebrity supporters
