If it wasn’t for Schoolhouse Rock I’d have had a much harder time memorizing my timetables. I still remember the words to many of those songs. In 1974 I got an additional treat as they used a Black Superhero to teach me about verbs. If memory serves, Black people showed up quite frequently in Schoolhouse Rock but the superhero Verb was powerful, cool, and never spoke a word. He only showed up for this one learning opportunity and never appeared anywhere else that I know of. Are you old enough to remember this?
