Watch Jimmy Fallon, The Roots And The Sesame Street Gang Sing The ‘Sesame Street’ Theme

Jimmy Fallon – who kind of looks like a Muppet himself – got the cast of Sesame Street in the studio tonight and his in-house live band The Roots to perform the classic “Sesame Street” theme song. And it is a-d-o-r-a-b-l-e.

If this doesn’t put a smile on your face I don’t know what will.
