Tonight's Picks: Dancer vs. Dancer, Corporate Food, and Johnny Cash in Jail

I walked the line.

Tonight we're watching the Man in Black -- and you should, too.

So You Think You Can Dance (8 p.m., FOX): The top 12 dancers will perform in a new episode -- and 3 will be eliminated. Will it be hip-hopper Ade? Ballerina Jeanine? Broadway boy Evan? Fret not, merengue-haters: a new episode of the more mildly-acronymed America's Got Talent (AGT) airs at the same time on NBC with plenty of magic tricks, mezzo-sopranos and middle-aged men to go around.

The Philanthropist (10 p.m., NBC): Main character Teddy Rist (British actor James Purefoy), who is loosely based on philanthropist Bobby Sager, jets off to a different exotic locale in each episode of this promising new show. This week, Rist ventures to Paris, discovers a sex-trafficking ring and devises a plan to rescue the victims.

The Daily Show with Jon Stewart (11 p.m., Comedy Central): Stewart will interview Robert Kenner, director of the new and controversial film Food, Inc. Variety calls the film "a civilized horror movie for the socially conscious, the nutritionally curious and the hungry."

The Late Show with David Letterman (11:35 p.m., CBS): Singer and actress Queen Latifah will appear on Letterman just one day after speaking -- and mourning -- at Michael Jackson's public memorial service at Los Angeles' Staples Center. She'll also be touting her new album, Cue the Rain, released yesterday, but she'll undoubtedly have something to say about the memorial, too.

Johnny Cash in San Quentin (12:00 a.m., CMT): Be sure to catch this classic Johnny Cash performance at San Quentin State Prison in San Rafael, California. Recorded just one year after his groundbreaking concert for the inmates at Folsom Prison, the San Quentin show served an equally thankful, forgotten audience. The show contains staples of Johnny Cash's legendary canon: "I Walk The Line," "A Boy Named Sue" and "Folsom Prison Blues." Cash was joined in the concert by wife June Carter Cash, bassist Marshall Grant, drummer W.S. Holland and guitarist Carl Perkins, among other players.
