Schoolhouse Rock/Headscratchers


 * Who's the Asian kid in this picture? The first kid is the girl from "A Noun is a Person, Place or Thing." The second kid is the mysterious boy of Asian descent. The third kid is Schoolhouse Rocky in his "normal" form (akin to Billy Batson and Captain Marvel). The fourth kid is the girl from "Body Machine." Given that all of the kids are from the original run of videos in the late 70s, shouldn't the Asian boy be from a video too?
 * Considering the other kids appear in Grammar, Mathematics, and Science Rock songs; he probably appears briefly in America Rock.
 * In "Noun: Person, Place or Thing", why is Chubby Checker white?
