TONIGHT'S MUST-SEE

"Academy of Country Music's 40th Anniversary Celebration," 8 p.m., CBS. Tonight we get lots of music without the intervening awards. The performances are mainly by people currently on the charts — Kenny Chesney, Lee Ann Womack, Rascal Flatts, Reba McEntire, Trisha Yearwood and Montgomery Gentry. Also appearing are Barbara Mandrell, Mickey Gilley, Merle Haggard, Garth Brooks and others.

"Charles & Camilla: Whatever Love Means," 3 p.m., WE (Women's Entertainment); reruns at 5 p.m. Here's a fresh take on the royal marriage, which is decidedly pro-Camilla. Prince Charles (Laurence Fox) is portrayed as a decent chap who is too self-contained and self-centered. Camilla Shand (Olivia Poulet) is just whom he needs — extroverted, educated, casual and lustful. She marries someone else (becoming Camilla Parker Bowles), but remains his friend, confidante and sometimes mistress. She even becomes his matchmaker. Diana Spencer is portrayed briefly, going from shy to shrill.

OF NOTE

"The Life and Adventures of Santa Claus," 2 p.m., ABC Family. This starts a holiday-animation marathon that continues to midnight and beyond. Santa must get everlasting life in this animated tale.

"Love Comes Softly" (2003, 3 p.m.), "Love's Enduring Promise" (2004, 5 p.m.) and "Love's Long Journey" (new, 7 p.m.), Hallmark Channel. Here's a chance to catch the trilogy in one burst. Michael Landon Jr., who shows his late father's skillful touch, directed, adapting Janette Oke novels about the frontier. In the first film, a widow (Katherine Heigl) heads West. In the second, her daughter (January Jones) is a frontier schoolteacher with two suitors. In the third, the daughter (now played by Erin Cottrell) begins a new life with her husband.

"Crossing Jordan," 7 p.m., NBC. This rerun sees Jordan, already battered by the flu, scrambling to find missing boys. That leads to a perilous adventure in an abandoned mine.

"Medium," 8 p.m., NBC. This rerun has a drug lord executed on the day his girlfriend is slain.

"Robert Klein: The Amorous Busboy of Decatur Avenue," 8 p.m., HBO. It was 30 years ago that Klein had HBO's first comedy special. Now he's not ducking the fact that he's no longer a hip, young comic. Klein, 63, begins the hour with a clever ballad about Viagra.

"A Very Barry Christmas," 9 p.m., ABC Family. In the midst of all those reruns, here is a new, animated special. Barry, a guy from Australia, and Santa Claus accidentally trade places.

"Law & Order: Special Victims Unit," 9 p.m., NBC. Here is another chance to see a terrific episode, with a deep performance by Mariska Hargitay. A young girl has called from a cell phone and claims she's being held captive. Some of the cops are skeptical until they make a startling discovery.

"Saturday Night Live," 10:30 p.m., NBC. Dane Cook hosts with James Blunt as musical guest.
