This Sesame Street footage of Stevie Wonder performing his own theme for the show has everything. Vocoders, long haired dancing kids, hip band, brown clad and spunky backing singers and a song you'll be singing for the rest of the week.
And here he is in the same session playing an el scorchio version of Superstition. Watch out for the hip as all get up kid on the balcony. He's goes off!
