President Barack Obama stunned the gathered crowds at a White House concert on Tuesday night (February 21, 2012) by joining in an all-star blues jam featuring Bb King and Mick Jagger. The performance, according to Reuters, was part of a PBS TV special, celebrating Black History Month. The performance is scheduled to be aired on February 27, 2012 as part of a show entitled 'In Performance at the White House: Red, White and Blues.'

In January, Obama performed at a Harlem fundraiser, singing a line from the Al Green classic 'Let's Stay Together'. During Tuesday night's jam, Buddy Guy cajoled the United States' President into singing, saying "We were trying to get you to help us sing. I heard you singing Al Green. So you started something. You got to keep it up now. You can do it." The Rolling Stones' singer Mick Jagger passed Obama the microphone and, smiling, sang a few lines from a verse of 'Sweet Home Chicago' in an understated manner, before handing the microphone back to the professionals. The legendary guitarist Jeff Beck was also playing during the jam.

Sales of Al Green's 'Let's Stay Together' reportedly rose by 490% the week after Obama sang it in January and a YouTube video of the President's musical moment has been viewed over 7 million times. In 1992, President Bill Clinton played a saxophone solo on the Arsenio Hall show, which is thought to have boosted the success of his presidential campaign.
