Meaning of "Three-Chord Circus" by Mischief Brew

The lyrics of "Three-Chord Circus" by Mischief Brew delve into the theme of nonconformity and rejecting societal expectations. The speaker describes their friends as eccentric and wild, engaging in dangerous and taboo activities that are frowned upon by society. The circus imagery used in the song symbolizes the idea of living on the fringes of society, perpetually underground and away from the mainstream. The repetition of the phrase "underground forever" emphasizes a sense of permanence in their outsider status. By addressing the listener as "Sir" and warning about it being too late to shield children from their influence, the speaker challenges authority figures who try to suppress their unconventional way of life. The mention of the Rat Parade and the Piper's tune at the end suggests a march towards rebellion and solidarity, as they find solace and companionship in each other despite being rejected by the world.
