Alicia Keys took to the piano at President Obama’s Commander in Chief Ball last night and modified the lyrics to her song “Girl on Fire” in tribute to the president and Michelle Obama.

“He’s living in a world and it’s on fire,” Keys sang on a medley that started with “New Day.” “Filled with catastrophe / But he knows he can find a way.” Later, the singer ad libbed, “Everybody knows Michelle is his girl / Together they run the world.”
