Did you really think that Billy Joel would appear on The Tonight Show Starring Jimmy Fallon without busting out an amazing song? The music legend and expectant father [1] sat down at his piano with Fallon on Wednesday night to take on the Rolling Stones classic "Beast of Burden." In a move that would make Jennifer Lawrence and Amy Schumer proud [2], the talk-show host danced on top of the piano while Joel pounded the keys, resulting in a performance that would surely win Mick Jagger's approval. Watch the video above, and then check out Fallon's amazing musical moment with the cast of Star Wars [3]!
