This Franck Pourcel album was released in Mexico in 1975. The title is the Spanish translation of the Broadway and film standard Singin' in the Rain.
I remember purchasing this LP and two other Pourcel albums at an El Paso, Texas thrift shop that was just a stone's throw from the border crossing to Juarez, Mexico. That was a number of years ago, before gang violence made Juarez a totally unsafe destination.
The quality of most Mexican LP pressings wasn't all that great and unfortunately that applies to the Pourcel albums even though they were released under the Odeon/EMI imprint.
Une fille aux yeux clairs (literally A Girl with Clear Eyes) comes from the LP pictured above and appears under the Spanish trnanslation, Una Muchacha de Ojos Claros. This was a pop hit for French singer Michel Sardou in 1974.

Cantando en la Lluvia was released on CD in Mexico in 2001, but I have no idea whether it's still in print. However, there are dozens of Frank Pourcel albums available on CD or as downloads, so if you like the big easy listening orchestras, you're sure to come across something that strikes your fancy.
Here's some interesting footage of a rehearsal by the Pourcel orchestra for a 1959 French TV show. Unfortunately the music track doesn't match the video, but worthwhile nonetheless.
