His 1972 appearance showed Americans what a beloved community could look like, integrated and full of promise

In a 1972 episode of Sesame Street, Jesse Jackson, then 31, is standing against a stoop on the soundstage modelled after an urban neighborhood block. He’s wearing a purple, white and black striped shirt, accented with a gold medallion featuring Martin Luther King Jr’s profile. The camera cuts to reveal a group of kids, the embodiment of Jackson’s Rainbow Coalition – children under the age of 10 from every ethnicity and racial group. He leads them in a call-and-response of his famous liberatory chant: “I am somebody.”

The adorable, cherub-cheeked kids light up the camera with their enthusiasm as they repeat the same words back to him. They are fidgety, giggly and powerful when they respond to Jackson in a cacophonous and slightly out-of-sync roar: I am somebody. The call-and-response is a wall of activating, energetic sound.
