TONIGHT'S MUST-SEE

"Grey's Anatomy," 8 p.m., ABC. In part, this is the pilot for a spinoff series that ABC could air next season. Addison travels to Los Angeles and meets her old medical-school colleagues, including ones played by Taye Diggs and Tim Daly. And in part, it's a standard "Grey's Anatomy" with relationship troubles. Meredith bonds with her stepmom (Mare Winningham), while Cristina hesitantly plans her wedding with her mom (Tsai Chin) and Burke's mom (Diahann Carroll). Also, Derek performs emergency surgery on Ava, formerly referred to as Jane Doe.

"CNN Presents: Larry King — 50 Years of Pop Culture," 3, 6 p.m., CNN. The network had scheduled a King week earlier, then scrapped it for Virginia Tech coverage. Now it tries again. King was 23 when he started at a small Miami radio station. Now, 50 years and two days later, Anderson Cooper and Ryan Seacrest host this special.
