Lost Seventies Mystery Click: The Darkest Song Ever Recorded?
I think Professor of Rock (on YouTube) claimed this song was so upsetting that people used to pull over to the side of the road when it came on the radio. It's about a fatal plane crash, but obviously it suggests a fatal car crash too, which could wig out a driver.
It's like one of those nasty 70s anti-war body horror movies. Not for the squeamish. I'm not even going to post the lyrics because they're upsetting too.
