Well, okay. Standard phrases with -ELS added, reclue wackily, and you have a theme. All three examples are quite well done, but with two 14-letter answers and one 15-letter, that's some 43 squares of theme, which seems a little light. I'm not typically big into revealers, but one here might have tied it together somehow.
Meanwhile, who doesn't like 36A: Henhouses of ill repute? (CHICKENBROTHELS). That's some silly stuff. Even better is 49A: The "I" and "o" "I do"? (MARRIAGEVOWELS). Hah! SECURITYCAMELS has a quite humorous visual, but not the same impact of the other two.
On the nice side, with so little theme, there's space for some really fun fill. I knew we were in for some good stuff when I hit 4D: "It'll never happen!" (FATCHANCE). Very nice. YOURMOVE and EASYTHERE were two more examples of fun little spoken phrases.
The other one, 35D: "Let's be serious here ..." was the site of my error. I had come across 41A: Nascar's Yarborough (CALE), when I had _ALE, and put a D in, essentially without thinking. When I finished the entire puzzle in the SE corner with 64A: Wicked Witch's home (WEST) and got the error message, I looked up and saw I had entered OHdOMENOW. As in "Oh, do me now!" That seemed just a tad inappropriate for the NYT. The real answer, OHCOMENOW, is much more in line. If I have to have an error, that's an error I'm happy to see!
The other zingy answer was KACHING, which I was happy to enter off of the K.
What's up with all the repeated answers recently? CLUE, ORION, OCHOA.
My kids would wince at 26D: Like a basted turkey (MOIST). That word is considered squinchy.
1A: Remove, as a hat (DOFF). B+. I love the word, and it was the only possible answer. Went right in.
Fave: ODETOJOY (38D: Schiller work adapted by Beethoven), as in his ninth symphony. You can never hear it too often.
Least fave: UEY (20A: One-eighty). You can never hear it too little.
Disregard any sense of dissatisfaction above. I liked this puzzle.
