TONIGHT'S MUST-SEE

"The Naked Brothers Band: The Movie," 1 p.m. and 5:30 p.m., Nickelodeon; also, series episodes, 2:30 p.m. There's a low-key charm to the movie and series that keeps you watching and smiling. Nat and Alex Wolff, now 12 and 9, are smart kids with musical talent and camera charm. That's no surprise: Their parents are Michael Wolff (Arsenio Hall's band leader) and actress-director Polly Draper. Draper created the movie, a mock documentary in which her sons pretend to be pop stars. She included her old "thirtysomething" cast mates, plus Julianne Moore, Tony Shalhoub, Uma Thurman and more. The result has a ragged appeal, and the series continues from there. Nat is portrayed as the pensive girl-magnet, Alex as a brash chap, their dad as a widower who wants to be an accordion star. Tonight's first five episodes are reruns, but a new one airs at 8. In that one, the brothers both write the same song, then try to remember where they heard it.

OF NOTE

"Kyle XY," 7 p.m., ABC. Here's a quick rerun of Monday's episode on ABC Family. Kyle is home, unaware that another young person from the lab (a girl, Jessi) is wandering in the woods, just as he did.

"Ghost Whisperer," 7 p.m., CBS. In a rerun, Melinda sees the spirit of a woman who died in a car crash 20 years ago.

"Bones," 7 p.m., Fox. This rerun has a body at a construction site, where chemicals have made it hard to identify.

"Standoff," 8 p.m., Fox. A polygamist has kidnapped his 17-year-old wife — who is also the daughter of his first wife. Complicating things, he's strapped dynamite to his body.

"Close to Home," 8 p.m., CBS. This rerun has a preacher killed. His wife is suspected, until a trail of missing church funds creates new possibilities.

"Las Vegas," 8 p.m., NBC. In a change, NBC is throwing in this busy rerun, complete with wedding plans, bachelor and bachelorette parties, and a bride who might change her mind. Guest stars include Dean Cain, Shawn Christian and Jerry O'Connell, plus music by Jennifer Nettles and Kristian Bush of Sugarland.

"Law and Order: Criminal Intent," 9 p.m., NBC. A re-creation of the Hamilton-Burr duel becomes way too authentic, when one of the men is killed. Police suspect it wasn't an accident.

"Numb3rs," 9 p.m., CBS. In a rerun, kidnappers tell a record-company mogul he has an hour to deliver $3 million.
