I love France Gall so this is a pretty fun part of the protest.
If you never heard her, you might recognize this song. I believe the April March (also an incredible artist) cover was in Death Proof and a few other movies or shows.
And you will also see some post about France - Wales (rugby Union) as Wales is Pays de Galles (Country of Wales) in French and we also call the France - Wales games France - Galles (and Galles and Gall have the same pronunciation in French).
