Hello!

Around the 57 min timemark, a French-speaking song starts. The title of the song is "C'est la ouate" - note that the the noun starts with an "o", not with a "q".
(At the time of writing this review, the song is listed as "C'est la quate" - that's why the spelling of the title is mentioned here.)

"la ouate" means "cotton" - an English translation of the French lyrics can be found here: https://lyricstranslate.com/de/cest-la-ouate-thats-cotton.html-0

The name of the French singer is Caroline Loeb. If you want to know more about her, read https://en.wikipedia.org/wiki/Caroline_Loeb.

Caroline Loeb's name is mentioned at the 61 min timemark; pronounced as if it were an English name.
Since she is French, this may be a hint how to pronounce her first name "Caroline" as a French name: https://en.wiktionary.org/wiki/Caroline#French. Her last name "Loeb" is pronounced similar to the name Sébastien Loeb whose pronunciation you can her here: https://de.forvo.com/word/s%C3%A9bastien_loeb/ (their last names are identical, so you will surely get the idea).

As said at the 61 min timemark, "C'est la ouate" was indeed a hit in Germany - more or less at the same time when other French songs were quite successful in Germany, for example "Ella Ella l'a" by France Gall, "Voyage Voyage" by Desireless, "Joe le taxi" by Vanessa Paradis, "Là-bas" by Jean-Jacques Goldman and Sirima, and "Étienne" by Guesch Patti (amongst others).
"C'est la ouate" by Carole Loeb was a Top Ten hit in Western Germany: it reached number 10 in the autumn of 1987 (see https://www.offiziellecharts.de/titel-details-52218 for the full chart history) - in the same chart week when the aforementioned "Voyage Voyage" by Desireless hit NUmber 1 (see https://www.offiziellecharts.de/charts/single/for-date-559825200000 - the chart week of 28th September,1987 in Western Germany).
