I liked this one. It played almost like a themeless, and I'm not sure I ever would have gotten the theme if not for the two-part revealer. Very nice overall, with a few (ok, one more than a few) obscure (at least to me) answers. ARRAU (25D: Pianist Claudio), PHILLIP (48A: Australia's Port ____ Bay), ROBB (47A: Eldest Stark child on "Game of Thrones"), and NHRA (38A: Drag racers' org.), were four I didn't know.
Much of the rest, though, was quite nice. COPPERHEAD (29D: *Anti-Civil War Northerner) sounds somewhat familiar, but I'd never have come up with it without crosses. And in other theme news, did you notice that "mimeOgraPh" fit in perfectly where CARBONCOPY (6D: *Typist's duplicate of old) belonged? I did, and it cost me a little time!
I always like seeing OCHS (3D: Protest singer Phil) in the grids. I know he has a convenient name, but we're also fans. And speaking of things I like, SCALLOP (40D: Bit of surf in surf and turf) (odd clue) doesn't get nearly enough play. In puzzles, or on my plate!
I think it's been a good week, but I've given it short shrift. Again, today, I'm very late with the review, and I feel pressure to just push the "Publish" button. Luckily, for me and for our readers, our faithful commenters have added nicely, as they always do. Thanks, guys!
Now that our brief travels are over, I hope to be able to devote more time to "the turn," and, indeed, to all future puzzles.
