Obama Sings "Chain Of Fools" To Aretha Franklin (VIDEO)

Long before her performance at the inauguration, and the fashion craze that followed (the Smithsonian recently requested her hat), Barack Obama was singing Aretha Franklin's praises--literally. In this video from a campaign stop in Detroit on September 1st, Obama thanked "the queen of soul," who was in the audience, and then sang the chorus of "Chain of Fools" while rhythmically bobbing his head.

How would you rate the President's voice?
