Elliott mentions that one of the back up singers is the daughter of Donny Hathaway, whose song Elliott sang.
The song Elliott sang was the first song he ever sang for American Idol, during the producer's round, which are not aired on TV.
Actresses Tori Spelling, Selma Ward, Joely Fisher, actor Kevin Nealon, and olympic figure skater Sasha Cohen were all in the audience.
Ryan: It's an emotional roller coaster ladies and gentlemen.
Simon (To Katharine): By choosing that song, it is like coming out here and saying 'I am as good as Whitney Houston'. You're not.
Simon (To Elliott): Seven weeks ago, I said you were one of the best male vocalists we've ever had on 'Idol'. Tonight, in parts, it was like a master class. It was superb.
Each contestant had two numbers that could be called. This is the first time that more than one number appeared when only one song has been sung.
Simon's critique of Kellie was cut off by the music that cues Ryan because he had gone on too long.
Andrea Bocelli and David Foster were featured helping out the contestants with their songs.
Love songs choices were as follows:
Katharine McPhee: I Have Nothing - Whitney Houston

Kellie Pickler: Unchained Melody - The Righteous Brothers
