TODAY'S MUST-SEE

Football, 3 p.m., ABC. For Missouri (11-1), everything is on the line here. It faces Oklahoma (10-2) for the Big 12 championship, but there's more. Already ranked No. 1 in the nation, Missouri needs to win to cinch a spot in the national-championship game, Jan. 7. Its opponent would likely be West Virginia (10-1), if it beats Pittsburgh (4-7) today.

Football, 6:30 p.m., ESPN2. Live from Aloha Stadium, the University of Hawai'i Warriors face the University of Washington Huskies.

"Radio City Music Hall's 75th Anniversary," 7 p.m., NBC. Don Hewitt has never misled us, so we'll take his word for it. This is "maybe the most spectacular show of its kind anywhere on Earth," he said. Hewitt, who turns 85 this month, ran "60 Minutes" for decades. He also says he's always been a fan of the Music Hall show and its dancers. "They're Americana. The Rockettes are like West Point cadets." Now he's produced this hour. He filmed three performances with nine cameras, then edited the show to half its length.

OF NOTE

"Higglytown Heroes" (6:30 a.m.), "Johnny and the Sprites" (7:30 a.m.) and "My Friends Tigger & Pooh" (8 a.m.), Disney Channel. All three have new, winter-themed episodes. "Johnny," an excellent show, even has a new holiday song from Stephen Schwartz, the "Wicked" composer.

"25 Days of Christmas" opener, 7:30 a.m., ABC Family. For the 10th year, this channel floods December with Christmas shows. That starts with "Christmas Every Day" (1996) at 7:30 a.m.; "Santa Who?" (2000, Leslie Nielsen as an amnesiac Claus) at 9:30; "Richie Rich's Christmas Wish" (1998) at 11:30; and the Arnold Schwarzenegger comedy "Jingle All the Way" (1996) at 1:30 p.m. ABC Family also counts two Harry Potter films — "Sorcerer's Stone" (2001) at 3:30 p.m. and "Chamber of Secrets" (2002) at 7.

"Jesse Stone: Sea Change" (2007), 7 p.m., CBS. This quiet film returns Tom Selleck to his role as Stone, a former Los Angeles cop, now a small-town police chief. While struggling with alcoholism, he reopens a 1992 shooting case and follows up on a teen's rape charge. The result is slow but involving.

"Chuck," 8 p.m., NBC. In a quick rerun, Chuck tries to help an agent who's accused of being a rogue; meanwhile, his friend at the Buy More store prepares for the post-Thanksgiving rush.

"Law & Order: Special Victims Unit," 9 p.m., NBC. At first, parents feel their daughter may have been killed because her fiance is a CIA agent. Then deeper truths emerge.
