Fantasia supplied one of the great "American Idol" moments when she sang "Summertime." The season three champ visits the "Idol" results show at 8 p.m. Thursday on Fox. This time around, she performs her new single, "Lose to Win."

Season two runner-up Clay Aiken is back on "Idol," too. But the main business will be sending home one of the five finalists.

"Idol" did Amber Holcomb a big favor by scheduling her last of the five on Wednesday, and the judges ended the night with a standing ovation for her. The judges seemed to be signaling viewers: Keep Amber and let Janelle Arthur go. But will viewers see it that way?

Angie Miller had a terrific night Wednesday, but the two front-runners seem to be Candice Glover and Kree Harrison. If any of them go, it would be a major surprise.

Other highlights Thursday:

"Glee," at 9 on Fox, turns from current events (school shootings last week) to Broadway ("Funny Girl" this week). "Glee" is always better when it sticks to the music. Rachel (Lea Michele) tries out for "Funny Girl," a nod to speculation that Michele would be perfect for the role in a Broadway revival. But any actress will have to contend with the memory of Barbra Streisand's electrifying work as Fanny Brice. 

CBS is in reruns, but the network may be trying out scheduling for next season. Would you prefer "The Big Bang Theory" at 8 or 9? CBS presents the show at both times. The thinking is a later "Big Bang" might reach more viewers and turn TV's No. 1 sitcom into an even bigger hit. "Person of Interest" shifts to 10. Filling the other spots are "Two and a Half Men" in its regular 8:30 slot and "2 Broke Girls" at 9:30.

NBC delivers the Christmas episode of "Community" at 8. But the big twist is the show is interactive. Viewers who watch live can play "Community zeetag Bingo" via smartphones, tablets or laptop. You can go to zeebox.com to download a free zeebox application for the game that offers belated Christmas gifts.

NBC serves up back-to-back episodes of "Parks and Recreation" at 9. Patton Oswalt, who won many fans on "Justified," guest stars in the first one.

Cable has new comedy, too. TBS rolls out a fresh "Men at Work" at 10 between "Big Bang Theory" reruns. FX delivers new, back-to-back episodes of "Anger Management" at 9.

The CW delivers new episodes of "The Vampire Diaries" at 8 and "Beauty and the Beast" at 9. There's a new "Hannibal" at 10 on NBC. But "Grey's Anatomy" and "Scandal" are repeats on ABC.

For true-life drama, look to HBO at 8. The channel salutes the late British photojournalist Tim Hetherington with the documentary "Which Way Is the Front Line from Here? The Life and Time of Tim Hetherington." In April 2011, he was killed by mortar fire in Libya, where he was covering the civil war. Hetherington's close friend Sebastian Junger directed the documentary. They were co-directors on the Oscar-nominated "Restropo."
