The Idols were all taken to Graceland, the home of Elvis Presley, since his songs was the week's theme. They meet Precilla Presley (and Lisa-Marie off screen).
Actress Jeri Ryan, Season 4 contestant Niko Smith and actor Amaury Nolasco were all in the audience.
Paula: (to Chris after sing "Suspicious Minds") You forget how good that song is, until you hear Chris Daughtry sing it.
Paula: (to Elliot) I have the right to change my mind, that was your best performance ever!
Simon: It was manic.
Simon: I can sing, I can dance.
Paula: You can?
Ryan: Okay, Simon have you ever lived in the real world?
Simon (To Katharine): All across America, you hold auditions for theatrical performances. It looked like a desperate, manic audition.
Simon (To Chris): Sunglasses aside, that worked.
Simon (To Katharine): What I wanted was apple pie on its own. Instead I've got apple pie and a gallon of cream on top.
Simon (To Taylor): That was a terrible impersonation of Elvis Presley. The dancing was hideous and it was just karaoke with a capital K.
Simon (to Taylor): You have just sung your way into the semi-finals, young man.
Ryan (to Elliott): Did you see the moves Paula was making? I feel obligated to give her a dollar.
Simon (to Taylor Hicks): It is the final four; let's get real. In the real world, that would be a bad impersonation of Elvis.
