That's what I mean by a song being 'applicable'. It's a common thing for an existing song to be used, typically in television, as background to some kind of real or fictional narrative. For example some sportiing event, with its inbuilt narrative of triumph and failure, or a political event with a parallel narrative.

I can imagine that at some future time there might be a confusion, with people thinking tye song was about that event, when of course it wasn't - but it was applicable, and might be highly relevant as a way of understandng how it was viewed at the time.
