If I'm not mistaken, Judge Victor Fleming's last puzzle had no evidence of legal clues or answers. If that's the case, this makes two in a row.
The theme is revealed at 36A: What shall be first...or words that can precede 17-, 23-, 52- and 60-Across (THE LAST). When preceded by them, you have the name of a well-known book or movie...probably both.
17A: Guy ready to sing the national anthem? (MAN STANDING).
23A: Era ended by Vesuvius? (DAYS OF POMPEII). How many of you thought you had something wrong with II at the end?
52A: Belonging to a Hudson Valley tribe? (OF THE MOHICANS).
60A: Museum exhibit? (PICTURE SHOW). Here's a very young Cybill Shepherd as she appeared in the film...directed by a very young Peter Bogdanovich.
I struggled to stay awake to finish this. It was a nonstop day and I need to head to bed fairly soon.
Noteworthy answers include 14A: Massey of old movies (Ilona)...her third appearance in the last six weeks, 15A: Embassy figure (envoy), 20A: Meditation goal (oneness), 27A: Cold one, so to speak (beer), 33A: Kind of acid (oleic), 42A: Maker of the game Combat (Atari), 48A: Martini's partner (Rossi), 59A: Janis __, with the 1975 hit "At Seventeen" (Ian), 69A: Funny Fields (Totie), 3D: Unable to hit a pitch? (tone deaf), 6D: Bleep out (censor), 11D: Title brother in a 1973 Elton John hit (Daniel), 12D: Mr. Gorgeous (Adonis), 25D: Negri of silent films (Pola), 40D: Former Texas governor Richards (Ann) and 45D: Unidentified planes (bogies).
My favorite answer...39D: Less than wonderful (not so hot).
I loved the cross of 39A: Vote against (nay) with 41D: Vote for (yea).
That's it for tonight. Here's the grid...
...and I'll see you tomorrow.
