Here's something to brighten up your day—or dare we say, "sweeping the clouds away": An adorable version of the Sesame Street theme song performed by Jimmy Fallon, The Roots and Big Bird, Snuffalupagus, Murray, Zoe, Count von Count, Cookie Monster, Elmo, Abby Cadabby and GROVER:

And here's Black Thought's rap in the middle of it (thank you to the HuffPo for the transcription!):

OK, you heard about, through word of mouth
Big Bird is out, he's in the house
He's turnin' up, with Snuffleup
They're really gettin' their hustle up
They stick together like Velcro
There Grover go, there's Elmo
And Cookie Monster there, look he likes
To take selfies with his cell phone
They got a homegirl named Abby
Her last name is Cadabby
I showed her my report card
She said, [Abby: Not too shabby!]
They got all types of cool kids there
It's lots of fun if you live there
One thing I keep forgettin' about Sesame Street...
How do you get there?

Fallon has been on Sesame Street numerous times—he played a Wild Nature Survival Guy and once discussed the word "inspect" with Elmo.
