TONIGHT'S MUST-SEE

"Studio 60 on the Sunset Strip," 9 p.m., NBC. This series started superbly, with Wes (Judd Hirsch) ranting on the air, then being fired. Now this flashback puts him on the other side: He's the responsible one, firing Matt and Danny. It's the second-to-last new episode of an impressive show that died young.

OF NOTE

"The Starter Wife," 6 p.m., USA Network. Molly tries to get Joan to stop drinking.

"The Office," 7 p.m., NBC. Here's the rerun of an expanded episode. Michael tries to perk up spirits by holding a casino night in the warehouse.

"The Office," 7:43 and 8:27 p.m., NBC. Here are two more expanded reruns, centering on word that one of the branches will be closed. In the first episode, workers dream of what their lives will be like when they no longer work at the office; in the second, the Scranton and Stamford branches merge. That puts Pam back near Jim — who loves her, but now has a Stamford girlfriend.

"CSI: Crime Scene Investigation," 8 p.m., CBS. Wrapping up a two-part rerun, Catherine tries to learn why she was kidnapped. Also, the team probes the murder of a fallen rock star, played by Danny Bonaduce.

"Grey's Anatomy," 8 and 9 p.m, ABC (barring basketball). In the first rerun, the shell-shocked Izzie tries to go back to work; in the second, she gets remarkable news from Denny's father. There's much more: George wants Callie out, Cristina tries to hide Burke's tremors, Meredith has a medical crisis ... and little Abigail Breslin (the "Little Miss Sunshine" Oscar nominee) plays a patient with a huge threshold of pain.

"Black Grace: From Cannon's Creek to Jacob's Pillow," 8 p.m., PBS. Black Grace is a dance group made up primarily of men who are Maori, the native tribe of New Zealand. Brilliantly choreographed by Neil Ieremia, they offer fresh and stunning work. They are so good that you might wish this hour had more dance and less talk.
