Here comes the boom

Billy Joel, John Leguizamo, Steve Wozniak and Erin Brockovich are among the eclectic people who make up "The Boomer List," a new documentary in which celebrities born from 1946 to 1964 share their personal stories about growing up in such an influential generation. 8 p.m. Tuesday, TPT, Ch. 2

Marching to New Orleans

"NCIS: New Orleans" gets off to a shaky start — and I'm not just talking about Scott Bakula's attempt at a Louisiana accent.
