Today’s Saturday Stumper

Today’s Newsday Saturday Stumper is credited to Zawistowski (Stella) and Agard (Erik). A tough puzzle, and I was delighted to find myself finishing it, from Z to A, so to speak.

Three clues that paired especially well with their answers: 9-D, four letters, “A lot of legal-size.” 36-A, four letters, “Where America’s day begins.” (IHOP? No.) 57-A, three letters, “Footwear from Oz.”

A clue whose answer made me startle, as I just read something about it somewhere (where?): 17-A, eight letters, “Spanish operatic genre.”

A clue whose answer seems to be a running Agard joke: 62-A, six letters, “They may be dueling.”

And a clue whose answer is a reminder that crosswords do indeed keep up with the culture: 67-A, eight letters, “Suited woman, perhaps.”

No spoilers: the answers are in the comments.
