The top 10 will take the stage tonight.
Counting down from 10 to one, the finalists from season eight of the Fox reality TV show "American Idol" will give repeat performances of show selections mixed in with new song renditions.
"(The audience) can expect to have a show of a lifetime," said seventh-place finalist Lil Rounds, "because everyone will be so great to not only watch, but to hear as well."
Tenth-place finisher Michael Sarver of Jasper, Texas, will kick off the concert with two numbers that might surprise those familiar with the singer, who will likely lend a country sound to Gavin DeGraw's pop song "In Love with a Girl" and Ne-Yo's funky "Closer."
Megan Joy, season eight's ninth-place finisher who hails from Utah, will give a repeat performance of "Put Your Records On," which she performed during the show, followed by a rendition of Amy Winehouse's "Tears Dry on their Own."
Also deviating from the songs he performed during the show is Arizona native Scott MacIntyre, who will take a seat at a piano for both Vanessa Carlton's "A Thousand Miles" and his rendition of "Bend and Break" by Keane.
Continuing the countdown from 10 to No. 1, Rounds, who said she hopes to have a record out by the beginning of 2010, will channel a few leading ladies of R&B with renditions of two Mary J. Blige tunes - "Be Without You," which she performed on the show, and "Just Fine" - along with Alicia Key's "No One" and Beyonce's upbeat anthem "Single Ladies."
"It is so fun to perform," Rounds said of "Single Ladies." "I have some choreography so I love to see people's reactions to my dancing."
Rounds will be followed by season eight Wild Card Anoop Desai, who was saved by the show's judges and became the first-ever top 13 Idol, will give repeat performances of Willie Nelson's "Always on My Mind" and Bobby Brown's "My Perogative," both songs he performed on the show, while offering a fresh rendition of the Ne-Yo tune "Mad."
Along with a shout-out to the state of Georgia with Ray Charles' "Georgia on My Mind," fifth-place finisher Matt Giraud will resume his show selection "You Found Me" by The Fray, while offering up a new take on The Black Crowes' "Hard to Handle."
Before the countdown to No. 1 continues, Idol finishers 10 through five will perform a group medley featuring renditions of "Can't Take My Eyes off You," "Tell Her About It," "Suspicious Minds" and "Beggin'" before red-haired rocker Allison Iraheta, who finished fourth in the competition, gives a repeat performance of Janis Joplin's "Cry Baby," along with rocking renditions of Pink's "So What" and Heart's "Barracuda."
Third-place finisher Danny Gokey's tour selections include Michael Jackson's "P.Y.T. (Pretty Young Thing)" and Rascal Flatts' "What Hurts the Most," both songs he performed on the show, with the addition of another Rascal Flatts tune, "My Wish," and Santana's "Maria, Maria."
Now to the moment many in the crowd will have been waiting for: raven-haired rocker Adam Lambert will take the stage for performances of Led Zeppelin's "Whole Lotta Love" and Tears for Fears' "Mad World," both songs from the show. Lambert will be joined by Iraheta for the duet "Slow Ride" before closing his portion of the concert with a medley of "Life on Mars?" "Fame" and "Let's Dance."
Lambert's performance will be followed by the 2009 American Idol himself, Kris Allen, with repeat performances of Kanye West's "Heartless" and Bill Withers' "Ain't No Sunshine," both show selections, and new selections "All These Things That I've Done" by The Killers, Matchbox Twenty's "Bright Lights" and closing with The Beatles' "Hey Jude."
Although Allen's portion of the concert will close the countdown from 10 to one, the mellow guitarist will be joined for a final group performance of Journey's "Don't Stop Believing."
