I didn't, and a GREAT mention. According to Wikipedia, one of the creators came up with the idea for the program after being puzzled over his son not memorizing multiplication tables while knowing all the lyrics to Rolling Stones songs. "Lolly, lolly, lolly get your adverbs here!"I almost forgot about Schoolhouse Rock!
I figured Chicago had to have a great market for this stuff. Metro areas were really communities back then.Growing up in the South Chicago Burbs, we had WGN TV which had some great local programming. Every morning was Ray Rayner and Friends and Garfield Goose, mid-day was Bozo's Circus, and on weekends was Family Classics with Frasier Thomas.
