The Curé of Ars on Dancing

I am looking for the *exact* quote (French O.K.) and source of a quote from St. John Vianney, which I vaguely recall is: > A dancer leaves their Guardian Angel at the door, and soon there are as many devils as dancers on the floor. A [similar question](https://christianity.stackexchange.com/questions/79375/reference-request-about-st-john-vianney-and-the-miraculous-medal) has previously been asked but the book *suggested* in the unaccepted answer does not contain the answer to the posed question. For years I have also been looking for the answer. But I believe the source for *this question*'s quote is more readily available; I just haven't come across it in a while.
