Whatever you think about President Obama, the man clearly enjoys singing.

From grabbing the mic to belt a few bars of "Sweet Home Chicago" with B.B. King  and Mick Jagger to slow jammin' the news with Jimmy Fallon, the president rarely has a smile as big as when he's singing -- even when he's slow jamming about interest rates.

On a more serious note, Obama broke into "Amazing Grace" while eulogizing South Carolina state Sen. Clementa Pinckney at Pinckney's funeral in Charleston, S.C., on Friday -- surprising even the audience there, who quickly joined him.

Here's four times we caught him with the mike and a tune. Speaking of tunes, we make no judgment on whether he can carry one. That, dear readers, is what comments sections are for.
