The NY Times announces "Obama Sings!"...but then I found out, the song was Lift Every Voice and Sing (aka The Black National Anthem). Of course he sang! I'm mad they cut the clip before the hard part. [NYT]
When I first moved to Chicago, I worked in Americorps on the south side of the city and found myself at many meetings and community events. Often, I'd be one of a handful of white people, so I'd try to be as inconspicuous as possible, which wasn't that hard except for the fact that I didn't know the words to this song. And this song was sung at... a lot of events.
