Although listening to that song now I find it somewhat sad and dispiriting, because the "change" that came in the decades following that proclamation, was it really a change? Looking at politics and society? I think of that song in the context of its use in "Watchmen" [0] as more realistic.
That film is without question my favourite set of opening credits, and honestly I think that short outdoes the rest of the film by an order of magnitude.
