Kez Ban, Breanna Steer, Angela Miller and Janelle Arthur pull a surprise on 'American Idol'

Nevertheless they attempt to perform “Somebody I Used to Know.“ It's a train wreck, even their parents in the audience are wincing. “Honestly, it was terrible,“ says Randy Jackson. Most of them didn't even remember the words. Half the group somehow manages to move on, but not Therinale.

A bunch of them try to write their lyrics on their hands or arms. Nicki Minaj shows the camera a shot of her hand, on which she's written, “They suck.“

Last up is Kez Ban's dysfunctional group; the rest of the group leave her at the hotel in the morning after she doesn't show. But you know, she can sing; leads off “Be My Baby” with a great tone and right in key; Breanna Steer next, then Angela Miller, with sultry Janelle Arthur finishing.

They're quite good; no choreography to speak of, and it's like a series of solo performances. But it's a good song choice and enjoyable to listen to.

Gets Minaj up on her feet. “The voices — perfection,“ she says. “I think all four, you're really special.“ In one of the only unanimous decisions of the day all four go on, with the judges calling them “the best group of the day.“

The group is shocked; based on all the drama it's a minor miracle, but they smartly didn't get in each other's way up there.
