President Obama sang a few lines from “Sweet Home Chicago” with blues greats B.B. King and Buddy Guy Tuesday night during a performance at the White House.

Performers included King, Guy, Mick Jagger and Jeff Beck. Jagger tweeted about his tour of the White House and posted a pair of photos.

The Rolling Stones’ frontman posted a message stating that he “had first rehearsal at #whitehouse today and had a lovely tour of the West Wing.” In another message, he wrote that Obama listened to a few of the practice tunes and appeared “really relaxed and happy.”
