Bohemian Rapshody-the lyrics were all over the place. Something tells me they put 3 ideas together, mixed it up and threw it up against the wall to see if it would stick.
But then what do I know?
IMHO, it's a Vietnam War protest song. Remember it was released in 1975. Young man killing a young man. Many of them drafted (caught in a landslide, if I'm not back again). Many soldiers died (too late my time has come, calling out to Mama like a lot of dying soldiers do, I don't wanna die). But we're supposed to be the enlightened and cultured ones (Galileo, Figaro). But our wars make us no different from the Muslims (Bismallah). And the different melodies and styles in the song, IMHO, represent what's supposed to be different cultures, yet in the end we're all warlike (again a Vietnam protest song).
I can't find anything to back this up, but I am sure I heard an interview with the band long ago that said, quite simply, it didn't mean a thing. Just tossed together.
I've never read a thing into them, but then I am often amused at critics' analysis of any kind of art, which tell more about the critic than the artist.
