Robert Plant Sings Doo-Wop On The Tonight Show!

Robert Plant stopped by The Tonight Show on Friday, and sung a little Doo-Wop with Jimmy Fallon! 

Jimmy loves to have fun with his guests, and with this bit they use an iPad app to record multiple tracks to make it sound as if they were an entire group.
