Last night, the President and First Lady hosted an all-star blues concert at the White House. There were a lot of famous musicians there—BB King, Buddy Guy, Mick Jagger, and more—but one man outshone them all: Barack Obama. At the end of the concert, the group started playing "Sweet Home Chicago" and roped the Prez into singing a few lines. His voice was smooth as ever, but the best part is the sly smile he gives as he's singing. Let's just say he's going to need to give his speeches in song from now on if he really wants to hold everyone's attention.
