President Obama has officially turned the being charming to get re-elected button on.

While speaking Thursday night at a fundraiser held at the Apollo Theater in Harlem, Obama sang a bit of Al Green's classic hit "Let's Stay Together." Watch the video above.

P.S.: Pre-2009, when Obama was still a US Senator, he belted out a Diane Warwick tune too.
