Finished except for 36a for which I have first and last letters and no ideas which fit the clue in any way. Hints?
In the print version there is a mistake in 45/65: 45 is 3, 4, 3 not 3, 3, 4. It confused me as I had the two crossers from 67 and 70 and could only think of one 4-letter word with them ... !
Quite demanding of knowledge for the thematics, and never heard of 7d, so a little googling and CrosswordSolver was needed. (49d is the only word fitting the 4 crossers I had, and I vaguely recognise it now I've seen it).
Any nudges for 36? Does "my" hint towards something to do with the word "maskarade"?
FOI: 70a
LoI(well, penultimate): 32 (learned a new word there).
Now to look at the regular Prize. Pot of tea first.
