Will Smith appeared on The Graham Norton Show earlier this evening to promote Men In Black 3 alongside Tom Jones and Gary Barlow. Conversation turned to The Fresh Prince of Bel-Air, and Smith performed the theme tune!

With a little help from the studio audience, and Take That front-man Gary Barlow on keyboard, the Hancock mega-star returned to his roots by telling us the story all about how his life got flipped, turned upside down.

So if you’d like to take a minute, just sit right there and watch the hilarious video below.

What do you think of the video – did it make you feel nostalgic?
