Tell us, did you also get bogged down in the NE? Frannie thinks that others will just rip through that quadrant, but I'm not so sure. I still don't really understand CLUSTERED (11D: Nearly set?). I kept thinking of concrete, but you couldn't say that that ever gets "clustered." I suppose you could say that runners at the start of a race are "clustered" around the starting line before "Set" is called, but is that fair cluing? What, dear reader, am I missing? Also, it didn't help that we had "moAn" for 11A: Kvetch (CRAB) for quite a while, and "ACTiii" instead of ACTTWO (24A: Setting for many reprises). Luckily, though, I knew TAMARIND (33A: Ingredient in Worcestershire sauce) from a GAMES magazine scavenger hunt that ran probably 30 years ago, at least. I think they asked for a food product that included both anchovies and tamarind. It's funny what things stick in your brain. Anyway, Frannie finally got the very nice ALLOWANCE (13D: Minor payment), and I pulled LILO (15A: Disney title character surnamed Pelekai) out of nowhere, and then we still fought for probably twenty minutes before I got UGLY (18A: Hostile). I then put in BOYWONDER (14D: Early riser?) because it fit, not because I understood the clue. I actually removed it before handing it over to Frannie, because I couldn't defend it and didn't want to embarrass myself. About a minute later, she handed it back to me with the "Well Done" message displayed. SHOW (21A: Lose one's place?) (hmm... I get it (horse racing), but that's a toughie) and the aforementioned CRAB were, I think, the last to fall.
In spite of our difficulties, and, really, also partly because of them, we enjoyed this puzzle. A good Saturday should have you scratching your head for a while. There was plenty of fun stuff, too, starting right at 1A: 1960s sitcom character with the catchphrase "I see nothing!" (SGTSCHULTZ). That went in immediately. As did TATIN (3D: Tarte ____ (French apple dessert). All that watching of Jacques Pépin is finally paying off! And speaking of Jacques, he would surely scoff at anyone making omelets using a hinged pan! (31D: Cookware that's often hinged (OMELETPAN)).
I never remember that 15A: Pitchblende, e.g. is a URANIUMORE until all the crosses pretty much force it. Love the words PAEAN (26A: Elated outpouring) and BUSHWHACK (29D: Clear one's way, in a way), and HATH (51A: Verb in the world's first telegraph message) was a fun bit of trivia. ("What hath God wrought?") "Wrought" would have been better, frankly. I'll put that into the notebook for our future crossword constructions.
I thought the Watergate was a hotel, not an apartment building, but I could be wrong about that. And if I were doing this alone, I'd still be scratching my head about ARGYLESOCK (61A: Accent for plus fours, often). Frannie tells me that the "plus fours" are a type of pant. According to the Wikipedia, "Plus-fours are breeches or trousers that extend 4 inches below the knee, and thus four inches longer than traditional knickerbockers, hence the name." So there you go.
Overall, a lot of interesting, fun, and hard clues with very little slop. A good Saturday.
