We overheard an officer say that the SFFD was prepared for 3,000 folks but the event promised 5,000 spots. So if you have a ticket, get down here now if it's not too late alrighty. Otherwise just come hang out on King. There's an afterparty hosted by Mos Def, Talib Kweli, Goapele and ?uestlove hosting at Mighty starting at 9pm. Look for Don Hazen's coverage of the announcement on Alternet, photos from the Examiner and the Chronicle tomorrow, Tara Silva in next week's San Francisco Magazine and Ari Berman's exhaustively researched piece in The Nation next month.

Update: More pics and our notes after the jump.
