WASHINGTON -- Mick Jagger, B.B. King and Jeff Beck teamed up with musical up-and-comers at the White House to celebrate the blues.
Jagger tweeted that President Barack Obama popped in during a rehearsal for Tuesday night's A-list concert and "seemed really relaxed and happy!"
Grammy-winner Keb Mo joked during a break in the rehearsal that Obama himself would be performing three numbers, and there could even be a record in the works. Mo joked that Obama's record would be called, "After the second term, now I can finally get my groove on."
Andrews said he got a chill just hearing King play a few notes during rehearsal. He added that he was hoping to learn something -- and maybe even borrow a few moves -- from the veterans in the group.
Even in rehearsal, Andrews said, Jagger "was in character right away like he was playing in a stadium, all the moves and things."
