December 4, 1971 –
During a Frank Zappa’s Mothers of Invention concert in Montreux, Switzerland, someone shoots off a flare gun which hits the wooden roof and quickly spreads. It eventually reaches the building’s heating system, causing an explosion. Luckily, everyone escapes.
The incident is later immortalized in the Deep Purple song Smoke On The Water.
A bizarre coincidence: On this date in 1993, Frank Zappa lost his battle with prostate cancer.
And so it goes
