Two of my personal favorites, Will Smith and Jimmy Fallon performed a live remix of the best sitcom theme songs of all time on The Tonight Show the other night. Including Will's classic Fresh Prince of Bel-Air theme.
Here's the list of all songs performed in order:
The Golden Girls
The Andy Griffith Show
I Dream of Jeannie
The Greatest American Hero
and of course, The Fresh Prince of Bel-Air!
