Excellent work! I spent an hour on it and got most of it done, but finally had to peek to finish it.
It really helps when you get the quote (is it a quote, or a tag line?)
Is it a convention that you are supposed to tell us when an answer consists of two words instead of one? I haven't done crosswords in years, but I seem to remember at least some clues would tell you if the answer was 2 words.
34A and 60A (especially) were groaners.
15D held me up, I'm not sure that's a word.
I don't get the joke in 43D.
Some of the last clues were too technical for me, 49D (though I might have got it), 55D, 58D (especially).
I'm guessing 56D should be an "acronym," not an abbr.??
Still, excellent work. These are hard to make.
