Do you think Jimmy Fallon does karaoke anymore? Or has being able to sing with the actual artists made it mundane? If so, last night he totally ruined "Stop Draggin' My Heart Around" for himself by dressing up as Tom Petty and singing it with freaking Stevie Nicks. As you can see below, they fairly faithfully recreated the song's video, right down to Petty's flower shirt. He still has "Islands in the Stream" – well, at least until he has Dolly Parton on.
