Video: Watch Jimmy Fallon sing ‘Duke of Earl’ with Robert Plant

If you were going to spend some time with Robert Plant, you’d find a way to sing with him, right? That’s just what Jimmy Fallon did when the singer stopped by “The Tonight Show” recently. The legendary Led Zeppelin frontman joined Jimmy for a quick iPad-enabled version of “Duke of Earl.” Plant looks a little confused by the iPad shenanigans, but is game enough for a quick barbershop quartet recording of the song. Is there anyone in the world who more obviously has his dream job than Jimmy Fallon? You might recall he did the same thing with Billy Joel for a quick cover of “The Lion Sleeps Tonight.” It’s apparently his go-to move with older musicians. Maybe next time Robert Plant will be up for a quick game of “Box of Lies.”
