I actually did a report on this during a Vietnam era history class.

The assignment was to choose a Vietnam era piece of anti-war art, a song about war, or if we could make a convincing argument to the teacher it could be something tangentially related.

I chose this song, even ran the lyrics by the teacher beforehand, and halfway through the song he realized it’s got gasp bad words in it and tried to actively censor it, which I thought was pretty funny.
