Perplexed? Have your questions resolved below.
Update: A few perplexities remain:
2 down: HHER 4-down (Presley) 27-across (hit)?
So what’s the Presley song?
4 down: The King makes rubberneck admit other revolt (7)
Has DA committed the cardinal sin: an indirect anagram? Here’s how I see this one: rubberneck admit other revolt = PRY admit ELSE revolt = PRY admit ESLE = PRESLEY = The King.
Is there a more elegant solution that doesn’t have DA looking like a flagrant indirect anagrammatiser?
