Although the Pink Floyd classic “Another Brick in the Wall (Part II)” has become a rallying cry for students who have become sick of going to school, Roger Waters says that’s not what the song is about.

“Even some intelligent writers thought it was an anti-education song and said it was disgusting and obscene,” Waters says. “But the song was never that. It’s a protest song against the tyranny of stupidity and oppression, not just in schools but universally. It’s about the malign influence of propaganda.”

Despite the misinterpretation of the song, Waters says he wouldn’t change a thing about it. “Listening to ‘Brick 2’ today, I wouldn’t touch a thing,” he says. “If you have something to do with a four-minute song that has proved to be as powerful as this one, you would have to be an idiot to tear the wings off to see what makes it fly.”
