From the Saturday Stumper

Aside from some tough stuff in the northeast corner, today’s Newsday Saturday Stumper, by Brad Wilber, is easy. Or E-Z. Pretty. Or very.

I was happy to see the clue for 15-Across, eight letters (a giveaway, at least for me): “‘Mother of the Blues’ who sang with Satchmo.” It might be more accurate to say that Louis Armstrong played in her band. For instance.

Another giveaway, 43-Down, seven letters: “Find rain in Iran, e.g.”

And a trickier clue, 67-Across, eight letters: “Setting for many mass movements.” WORKSITE? No. And no spoilers. The answers are in the comments.
