Le café est dans les tasses
Les cafés nettoient leurs glaces
Et sur le boulevard Montparnasse
La gare n’est plus qu’une carcasse

Il est cinq heures
Paris s’éveille
Paris s’éveille

This is the song that comes to mind when I think about Paris being resilient after Friday’s attacks. Paris, s’éveille. 

(Here are translations of the lyrics: The German one is a bit closer to the feeling of the song than the English one. I need to brush up my French.)
