More photographs, this time from people who know what they're doing, ie., photographers. There's a certain spirited randomness to the lineup of famous figures taking to the microphone in between the songs here today: one moment it's Martin Luther King III, speaking on the steps of the Lincoln Memorial, just as his father did; the next, it's Steve Carrell, from the American version of The Office, who doesn't bring quite the same historical resonance. But he seemed to be enjoying himself.
UPDATE: The prepared text of Obama's remarks at the concert.
