Let me just say that Sean Paul is a bad ass. He's an insanely talented dude.
In 2009, I had the honor of doing a studio session with Sean Paul, where he came in, laid down vocals for a custom version of his song "So Fine" for 95.7 The Beat, then I produced it with the instrumental.
Watch how on-point he is! The only thing that's written down on that paper he's holding was the name of the station, and all he has is the instrumental. And he nails it in one take!!
