Barack and roll!

President Barack Obama showed off his pipes again Tuesday night -- joining music icons Mick Jagger, 68, B.B. King, 86, and Buddy Guy, 75, for a surprise performance of "Sweet Home Chicago" at a White House Black History Month blues concert.

"I heard you singing Al Green. So, you've started something," Guy told Obama, 50, referencing his recent performance of "Let’s Stay Together" at Harlem’s Apollo Theater. "You've got to keep it up now!"

And after Jagger handed over the mic, the President was quick to comply, belting out a few bars of the ode to his hometown.

Despite the impromptu performances, Obama isn't dusting off a spot in The Oval Office for a Grammy. "I don't want to lose any further votes because of my singing voice," he quipped earlier this month.

The entire concert, part of the "In Performance at the White House" series, will air on local PBS stations on February 27, at 9 p.m. EST.
