Glendale Music School Banner - The Jackson Five and Carol Burnett
A banner from the Glendale Music School can be seen in a short comedy sketch featuring Carol Brunett and the Jackson 5. It has a white background and funky Fleur-De-Li's like symbol. In this video the classroom banners have been reversed so they face the camera the correct way, so they can be read.
During age of television or one way media, things were different but not so different. Classroom shenanigans and smart mouthing has been around since before TV and radio, but back then their were harsh consequences for being a showboat.
But when teachers are able to turn up and expand previously unreachable minds, the Earth will certainly feel like it's moving.
