Another tough, tricky puzzle! Lots of great clues in here, and lots of ways to go wrong. I put in "looS" for IANS (5D: Johns of Britain), which might have contributed to the NW being the last to fall today. I kept doubting it, but it seemed so right… I even took it out to put in ANOMALY (14A: It's not normal) at one point, but I ended up taking out the correct answer again to put back the wrong one! Finally, Frannie got ONETOOMANY (2D: Drink that often makes a person sick) (reminds me of the classic George Burns joke - "It only takes one drink to get me drunk. The trouble is, I can't remember if it's the thirteenth or the fourteenth."), and MOTORCYCLE (3D: Road hog) (nice), and then ANOMALY had to be right. ZOMBIE (1A: Body that doesn't remain at rest) (I had "mObilE" in there for a while) was also slow to come, but is a nice pair with the lovely clue 26D: Restin' piece (TAPS). In the lower half of that section, I plunked down TACITUS (39A: Writer of the ethnography "Germania") without hesitation or crosses, and ATO (19A: ____ B) seemed almost too easy, but for a long time, that's all we had there. Never heard of ROCCO (27A: Chef DiSpirito), but after a while, it was all that made sense.
There was very little junk here, save, perhaps, the unclassy classic ELHI (42D: Primary and secondary, briefly), but it's nice to have such a gimme on a Saturday. I didn't love MUTISM (10D: Refusal to speak), nor WORDOFGOD for 8D: Bible. If ever a clue called for a question mark!… Also, the Americanos that I know contain espresso and water. I don't know what kind has SODA (20A: Ingredient in an Americano). And finally, I would have preferred either WNBA for LPGA (36A: Org. for female shooters), or a slightly different wording. Do golfers really "shoot?" Well, I suppose they "shoot for the pin," but it seems a stretch, even for Saturday.
But I digress. The cluing was, as stated earlier, on the whole, very clever - 68A: Producing zip (STERILE), 15D: Demonstrate a wide range on a range? (YODEL), 18A: Rare electee (WRITEIN), and 46A: Get off the drive, say (DELETE), to cite just a few. And who doesn't love a nice "Ninny" crossing of NUMBSKULL and BOOB?
It was a fight all the way, but that's just what we're looking for on a Saturday morning. Very nice.
