American Idol birth year theme: Performances air 8 p.m. tonight

The eight "American Idol" finalists will perform songs from their birth years on tonight's episode, which airs 8 p.m. on Fox.

If the theme alone doesn't lure you, get excited about this: It's the first one-hour Tuesday episode in a very long time.

Remaining singers are Adam Lambert, Danny Gokey, Allison Iraheta, Lil Rounds, Kris Allen, Scott MacIntyre, Anoop Desai and Matt Giraud.

Check out the Ledger's "Idol" blog for reporter Sonya Sorich's song predictions. As usual, she'll update the blog "live" during tonight's show, so visit the site often for updates.
