Sure, and the highlighed is my point. Even something that was actually about the incident has more or less lost that connection in many people's minds.
I would say very few people under the age of 40, if they even hear the song, would make the connection to a forgotten incident.
Personally, these days the song makes me think of a main character on "The 100" who was constantly singing the song for days before he and a group of people committed mass suicide rather than face the latest crisis on post-apocalyptic Earth.
