Finished,and it was fun,but can anyone just hint at the explanations for 18a ("statue that came to dinner")and 20d ("don't come in yet!") without of course revealing too much at this stage of the game?
...to expand further: I see 2 poss. expl. for 18:the one is a specific centre in Wales with that name, the other a specific statue in Manila of Aquino.or is it a ref. to the Greek ....phae?
As for 20d, I'm now regarding that as solved!
