I guess when there are anniversaries one is likely to get overlap between crosswords on the same theme. The IQ one this w/e was slightly more elaborate, imo.
I'm doing fairly well, but haven't a Scooby about Ring 36... I'm surprised no-one has mentioned it here.
It's holding me up with the related radials, so a hint would be very welcome.
I see what you mean about Ring 33, lemon. The clue would surely have worked without the "apostrophe-s". Having said that, it didn't bother me at the time and it was the first clue I solved.
I think iratus's explanation works for me, although I'm not sure I'd say I'm a fan of the clue! I spent some time wondering if I was falling for a particularly ingenious red herring...
