Billy Joel and Jimmy Fallon Doo-Wop on the Tonight Show [VIDEO]
This is really cool from the Tonight Show. Billy Joel was Jimmy Fallon's guest the other night. Jimmy brought out an iPad and then the fun began.
Jimmy and Billy loop their voices on the iPad app to form a 2-man doo-wop group -- singing "The Lion Sleeps Tonight" by The Tokens in 4-part harmony.
