American Idol season 8 Top 11 features Grand Ole Opry theme.

After singing Michael Jackson songs last week, the American Idol season 8 finalists took the Grand Ole Opry theme during this week’s performance night.

Among those who gave impressive performances that also wowed the judges is Matt Giraud who gave a different flavor to the Carrie Underwood song “So Small”, Anoop Desai who came back from a lackluster performance last week with his take of the song "Always on My Mind", Kris Allen also gave a good rendition of “To Make You Feel My Love” and Megan Joy Corkrey who sang "Walking After Midnight" by Patsy Cline who is not even feeling well.

Simon Cowell, one of the judges, said that Giraud, the 23-year-old piano player from Kalamazoo, Mich., even outsang Idol favorite Danny Gokey with his heartfelt take on a Carrie Underwood song.

"I don't think you've had enough credit, actually, for your vocals in this competition so far because everyone's been talking about Danny and Adam (Lambert)," Cowell told Giraud who even compared the singer to Michael Buble.

One of the 11 contestants will go home on tomorrow’s elimination night unless the judges unanimously decide to use their power to save a contestant based on the new rule.
