FUN. Brings Sexy Fun Time To David Letterman!

OH Dave, YOU set the world on fire… with your teatime late night chats and silly jokes!
Last night on the Late Show with David Letterman, those rowdy boys from FUN. played their only song megahit We Are Young and David Letterman got his aging a** up on stage and raged’ out!
HAH JK!
But that would have amped this performance up a bagillion times.
Watch David Letterman NOT get in on the action (above).
And even though this song has been so overplayed it’s almost unbearable, we still LURVE it!
