Naturally, since I know very little about this musical period (which is why I posted, so I can pull more of this together. Someday), I took the "Mr. Lady-MWMF" to Dr. Google. Well, actually, Duck Duck Go. But anyway, one of the links was this one, explaining the situation.

Oh. I see.

Frere-Jones doesn't mention it. Bad critic!

Anyway, thanks for the information.
