Idol': Marc Anthony with Sheila E and Jennifer Lopez, then Tom Jones

 Ryan Seacrest brings back Joe Repka, the would-be radio announcer, who takes us through a series of the season's worst auditions.
After that, Marc Anthony, who has played a big behind-the-scenes role all season, gets his moment on the stage. That's Sheila E playing percussion with him. And that's Jennifer Lopez in the white fringe-y outfit dancing around and trying to distract him while he's singing.
Next, we get wrestler-style rants from Casey Abrams and James Durbin about whose elimination was the more shocking. Pia Toscano helps them settle that argument.
While the girls got a Beyonce medley, the guys get one consisting of Tom Jones: Kiss, She's a Lady. And, of course, we've all wanted to hear James Durbin sing What's New, Pussycat? It's a hot mess, but not as messy as Scotty McCreery's rendition of Green, Green Grass of Home. Jacob Lusk raises the entertainment factor with Love Me Tonight, complete with mariachi horns, and Casey Abrams mugs his way through Delilah, then introduces Jones for It's Not Unusual.
