What about the children?

I'd seen it only once, followed by decades of feverish, fruitless searching. I began to doubt my memory and in the end, my sanity. But my white whale has finally surfaced on YouTube. Yes, it's Stevie Wonder at the pinnacle of his career playing an astounding live extended jam of his greatest song with an awesome band (including Ray "Ghostbusters" Parker on rhythm guitar and hat) for an audience of 7-year olds on Sesame Street in 1973. Amazingly, the brilliance of the performance is almost upstaged by the wild child on the fire escape who seems to be having a funktasm. The whole thing just makes me smile crazily and mourn the days when Sesame Street was interesting and brought the funk to the little children.
