Obama's got the moves like Jagger

President Obama helping Blues legend B.B. King on stage.
Barack Obama joined Mick Jagger on stage for a bit of blues Tuesday night.
The crooning president reunited with the microphone just a month after singing at a New York fundraiser.
This time he shared top billing with the Rolling Stones frontman to the delight of First Lady Michelle.
The couple were hosting a tribute concert to blues music as part of Black History Month with legendary blues star B.B. King also in the line-up.
It is only a week since the president said he would not be making any more public appearances — in case it lost him votes.
Obama earlier joked that sometimes being the president is a tough gig.
He said: "Some nights when you want to just go out and take a walk, clear your head... Secret Service won't let you, and that's frustrating.
"Then there are other nights when Mick Jagger and B.B. King come over to your house and play a concert. So I guess things even out a little bit."
