From 1971, here's Jessie Jackson on Sesame Street doing a call-and-response with the children of the poem I Am - Somebody.
I Am
Somebody
I Am
Somebody
I May Be Poor
But I Am
Somebody
I May Be Young
But I Am
Somebody
I May Be On Welfare
But I Am
Somebody
It's difficult to imagine something like this airing on the show now. Sesame Street was originally designed to serve the needs of children in low-income homes, but now the newest episodes of the show air first on HBO...a trickle-down educational experience. (via @kathrynyu)
