Wiz Khalifa performed his recent Akon-assisted release "Let it Go," on Leno, for which he raps passionately in front of a live band, with the help of a long, flowing scarf attached to his microphone. It must have been very windy in there. The audience claps along as he raps about having a kid and asking "the green man" for more ounces, among other things.

Watch and discover what the clean version of a Wiz song sounds like.
