Its being aired on a whole bunch of channels tonight, online, and on 2 SiriusXM channels (Pearl Jam Radion and E Street Radio). Springsteen opens the show at 7:30. Paul McCartney is supposedly closing the show and will be playing at least 1 song with Dave Grohl and Kris Noveselic (or however you spell it. Roger Waters is playing a few songs and will perform "Comfortably Numb" with Eddie Vedder. (1/2 of) The Who are playing and so are the Rolling Stones, Bon Jovi, Billy Joel, and Eric Clapton. I'm sure there are others. The show is supposed to end sometime around midnight.
