And yes, of course it ends with the 'Fresh Prince' theme. It would have been criminal if they didn't.

Will Smith joined Jimmy Fallon for a chat and a yarn (via drone and some strangely placed cameras to promote his YouTube channel because yes, he's a YouTuber now) on 'The Tonight Show' last night and after their camera shenanigans, they performed a live remix of some of the best sitcom theme songs of all time, including 'The Golden Girls', 'Diff'rent Strokes', 'I Dream of Jeannie', 'Full House', 'The Greatest American Hero' and more.

But the pièce de résistance was of course the live version of 'The Fresh Prince of Bel-Air' which just never gets old.
