The crowds are in place for the Obama inaugural concert at the Lincoln Memorial. While the concert begins at 2 p.m., it won’t be on television until 7 p.m., on HBO, which is broadcasting over an open signal for the show. For those who want an audio preview of what’s being billed as the inauguration’s “opening celebration,” it’ll be broadcast live on NPR. Performers include Beyoncé, Mary J. Blige, Bono, Sheryl Crow, Herbie Hancock, Usher, Shakira, Bruce Springsteen, and Stevie Wonder, among many others. On tap for Martin Luther King Jr. Day tomorrow: a Kids’ Inaugural concert to honor military families, which is being shown live on the Disney Channel.
