I filled out the grid in 4:29! But I didn’t do it correctly. It’s a common theme for me when I race through it.

Like the Moody Blues say: “Run like a fire / Don’t you run in / In the lanes / RUN FOR TIME.”

It took almost as long to find my errors as it did to do the puzzle!

I pulled out 47D Unleavened bread for Passover: MATZOH as today’s clue I have something to say about. Transliterated words are the really the worst. I have seen MATZAH and MATZO in the wild and in use, but MATZOH? I don’t think so. It’s like when the Spelling Bee had MAZAL and MAZEL as words that existed in the grid but not in the word list. But they’re fine with MOOLA AND MOOLAH. These inconsistencies are quite a headache.

And as for the theme: 62D Two forms of them are found in 18-, 38- and 60-Across: IDS.

Though I prefer my own theme and the one I started with: RIDE MY SEE-SAW!
