I don’t think the fact that most of us Americans couldn’t give a whit about British class warfare detracts from this song a bit. That the lyrics are meaningless to a good chunk of the audience is probably a plus–the lack of comprehensibility transforms what might be an annoying political rant into just a great rock and roll song. No agenda needed nor requested.
Sorry about the annoying video. It’s the best I could find. Do yourself a favor and switch to another tab or window while listening.
