President Barack Obama once again showed off his vocal talents by singing 'Sweet Home Chicago' during a blues concert at the White House on Tuesday night. How did the performance compare to the Commander-in-Chief's rendition of Al Green's 'Let's Stay Together' last month? Watch below and decide.

Obama has just finished thanking all the musicians who attended the concert, which included Jeff Beck, B.B. King and Mick Jagger, when legendary blues man Buddy Guy goaded him into singing the blues classic. "I heard you singing Al Green," Guy said. "You've started something. You've got to keep it up now."

At first, Obama tried to refuse. But then, Jagger passed the microphone and the POTUS launched into a surprisingly tuneful rendition. What do you think? Could Obama have a second career as a blues singer?
