The song was a Top 5 hit in the UK and really is Anglo-centric so it probably has no audience beyond the UK.
As much of his early work, "Oliver's Army" is satire about a right-wing paramilitary group. Oddly enough, the person quoted in the song is angry about non-whites immigrating to Britain and slowly taking over. (Hmm, guess they were right).
But Elvis then dismisses their rough talk:
But there's no danger. It's a professional career.
Though it can be arranged with just a word in Mr. Churchill's ear
If you're out of luck or out of work
We can send you to Johannesburg.

I just hope the feminists don't go after "Pump It Up".
He’s a leftist first and foremost so none of this is a surprise. I saw him in concert back in his prime a couple of times and his shows were good energetic fun. That said apart from the odd bit of news like this I haven’t thought about him in decades. I’ve pretty much shut down left wing entertainment for myself so I won’t ever be attending a current self censored show by Declan.
Grinning bigtime! :)
