President Barack Obama is officially THE COOLEST president to ever take office in the history of the United States of America!

While speaking on stage Thursday (Jan 19) at a fundraiser at the world-famous Apollo Theater in New York, President O broke out into song, and sang a line from Al Green‘s classic hit “Let’s Stay Together” after thanking the music legend for attending the charity event.

“Don’t worry Rev I can not sing like you, but I just wanted to show my appreciation,” President Obama said afterwards, adding that his staff didn’t believe he would actually go through with it.
