From my TV perspective, it looked like a huge crowd on the Mall. It was overwhelming white. And — I'm not lying — I wrote "overwhelmingly" before I remembered that "overwhelmingly white" had become a hilariously common way to refer to crowds drawn to conservative rallies.
The crowd also looked pretty young and disproportionately male. Because it's comedy?
UPDATE: Ed Morissey has video of the Cat Stevens performance and a good summary of the controversy — which also comes up in the comments to my post — about presenting Stevens as an emissary of peace when he spoke with some degree of approval of the fatwa against Salman Rushdie.
UPDATE 2: Tobin Harshaw collects opinion about the larger event.
