AUDIO: Peter Horton on "Grey's," "6 Degrees"

Earlier this week, I chatted with Peter Horton, the former "thirtysomething" and "Brimstone" star who's now behind the scenes at ABC's hottest show, "Grey's Anatomy," airing at 8 CT tonight in its new time period. He talked about "Grey's" and why he was brought in to shore up "Six Degrees" after the pilot. He also discussed — cryptically, of course — how this season of "Grey's" will transpire, and though he couldn't get too detailed, he made one thing clear: Things move faster on the mainland than they did last year on "Lost."
