In 6th grade my music teacher took us all to her house during school hours to watch The Wall. [this was early 80s].
She taught us how to sing “Another brick in the wall” in class.
About a month later, she was no longer our music teacher and we weren’t allowed to sing that song in the hallways.
Could be coincidence. “We don’t need no education..”
I guess they thought we’d flip over desks and burn the school down or something. I dunno.
