Soon after 9/11, Paul McCartney organized the Concert for New York City to benefit first responders. He also funded a documentary about his effort, but the footage hasn't been seen until now -- for good reason. There are a few exciting music snippets (Jay-Z), but cameras mostly show McCartney signing autographs, holding court and fawning over Bill Clinton and other big names backstage. Who wants to see the beloved rocker gush to Jim Carrey, "You're fantastic?" (Showtime, 9 p.m.)
