A few months ago President Obama became a viral sensation after singing a verse of Al Green's "Let's Stay Together".  Last night the President once again showed his vocal abilities when he joined Buddy Guy and B.B. King for a few lines of "Sweet Home Chicago".

The concert took place at the White House as part of the White House Concert Series.  This particular performance was to showcase the blues as part of Black History Month.  Check out the video below!

Now compare that with his performance of "Let's Stay Together":

"Let's Stay Together" or "Sweet Home Chicago"?

Which of the President's performances do you prefer?
