This Veterans Day concert is a big deal, as some of the names on the scheduled performance list can attest: Bruce Springsteen, the Black Keys, Dave Grohl, Eminem, Rihanna and Carrie Underwood, for starters. And as onstage hosts, Jack Black, Bryan Cranston, Jamie Foxx, John Oliver and others. Record it, because there are no plans, at present, to release it on DVD or CD.
