Today’s Saturday Stumper

Today’s Newsday Saturday Stumper, by Frank Longo, was tough. I stared and stared, and now and then a word suggested itself as right. I finished in forty-seven minutes — after practically going to sleep with quandariness, as Frank O’Hara might have, if he had tried this puzzle.

Three clues that I especially liked: 8-Across, six letters, “Racket clubs.” 22-Down, six letters, “Scorch with pans.” 47-Down, five letters, “David : Milhous :: Delano :     .” That last clue is not especially tricky, but it’s quietly disorienting. And it woke me up.

No spoilers; the answers are in the comments.
