Billy Joel & Jimmy Fallon Form Doo-Wop Group, Sing 'Lion Sleeps Tonight' with Help of iPad App!

Jimmy Fallon gets quite the treat when he forms a doo-wop group with the legendary Billy Joel on The Tonight Show Starring Jimmy Fallon held at Rockefeller Center on Thursday (March 20) in New York City.

With the help of a handy iPad app, the Looper, the duo were able to belt out “The Lion Sleeps Tonight” with full backup vocals!

“To sing with you is the craziest thing,” Jimmy gushed before presenting the idea.
