Man, what a nice Wednesday puzzle! It took me forever to see TROU (14A: Drop ____ (start to strip)), and then a little longer to actually believe that they would use that, but when it finally went in, I was quite happy.
Other than that, the top was a little lackluster. Somewhat difficult clues for OTHER (1D: Remaining) and ARENA (2D: Where the action is) kept things open up there for a while, but I liked the back-to-back French of ENTRE (20A: ____ nous) and OUI (21A: French vote). Also, just after bashing themes yesterday, I have to admit that I really enjoyed this one. They skew old, but hey, I'm old, and I watched all of these when they were actually airing except for the Jackie Gleason Show. I have a special fondness for AONEANDATWO (24A: Lawrence Welk intro words), because my sister and I used to watch that at my grandparents' house. Well, Sue and I would mostly be coloring in coloring books on the floor in front of the TV, but we'd look up occasionally, and the music, of course, didn't need looking at.
I give Mr. Mueller extra credit for coming up with a new (albeit impossible) clue for ENO (33A: Will ____, "The Realistic Joneses" playwright), and I also enjoyed the paired art clues 35A: Setting for many van Gogh paintings (ARLES) and 70A: Settings of Delacroix and Ingres paintings (HAREMS). Tough, that second one. STEAL (48A: Diamond datum), too, was quite difficult, especially as "karat" also fits there.
There's a lot good in here. The Emerson quote, the classical reference to Icarus... and I just had a good feeling about it.
I'll say it again - a nice Wednesday.
