On of my favorites because it's a racket! I love how Phil's voice sounds like it's being overwhelmed in the mix when he shouts "maaaaaaaaaaaaan of our tiiiimes", plus the bit where he's singing something I can't make out (sounds like "an enemy <something something>"). And the effective pauses dropped in here and there. The tense keyboard notes that loom ominously in the background in parts.
As regards the thread, I'm partial to cryptic lyrics also.
I quite agree with that. Strange song, but there's something I like in it, the musical tension that goes through, only released when the drum pattern changes at the very end.
Another set of cryptic lyrics is Abacab. The band itself explained that at the time they tended to write lyrics that sounded good rather than had any sense, but these ones are particularly obscure.
