I still don't think Waterloo City Hall qualifies as LoPo. It's more of a watered-down version of an 80s Jack Diamond vocabulary.
The Rose Theatre, though, absolutely qualifies--maybe it's (unfortunately) what WCH might have looked like had it been built a decade or two later. Really flyover-state Bush's AmeriKKKa in its vocabulary.
The tragedy of the US/Zephyr principled objection to Bobby Stoin's 1 St Tommy is that it'd apply much more appropriately to the Rose Theatre, to the point where even *I'd* side with them, to some extent...
