Jessica Sanchez and Phillip Phillips will compete for the "American Idol" crown on next week's finale. Joshua Ledet was eliminated on Thursday night's results show, and he sang James Brown's "It's a Man's, Man's, Man's World" for his farewell song. Some 90 million votes were cast to determine who made it to the top two.

The top three opened the show with a group performance of the Beatles' "Got to Get You into My Life."  In a segment apparently taped before contestant Hollie Cavanagh was eliminated, the top four went to 20th Century Fox Studios to lend their voices to a song from the upcoming movie "Ice Age: Continental Drift". Drake, Jennifer Lopez and Queen Latifah also sang on the track.

Songwriter Carole Bayer Sager and actress-turned-singer Rita Wilson sat by Jimmy Iovine in the audience and joined host Ryan Seacrest in remembering the late disco legend Donna Summer.

Lisa Marie Presley took the Idol stage for the first time to sing "You Ain't Seen Nothing Yet," and Idol alum Adam Lambert performed "Never Close Our Eyes" from his new album, Trespassing.

Jessica and Phillip will perform on American Idol Tuesday night at 8:00 Eastern on Fox. The Idol winner will be announced on Wednesday night's show.
