Today, very late (Sorry!), I am grateful for how my tax dollars go to help fund snow clearing personnel and equipment of really top notch efficiency. I can tell the difference when I cross the town line from Bethlehem, NY, to Albany, NY. Eighteen to twenty-four inches of snow is a ton of white stuff to move.
I only have a little time due to the aforementioned weather issues, clearing driveways, and chorus rehearsal. So let's note that the theme today is brilliant. Starting with the revealer, split across two answers of VOICE / ACTOR, and the way the other four theme answers' first words are now revealed to be a homonymic version of "heard but not seen," itself a twist on the classic instruction for poor neglected children.
And also BUTTDIALS. Tee hee.
I'll also note that 18A: Pebble in one's shoe, e.g. (ANNOYANCE) is symmetric to 58A: On and on and on ... (ADNAUSEAM). Seems apt.
There aren't any clues that made me perk up, but neither is there much to complain about in the fill, so I'll call this a fine Tuesday, and leave it at that.
