“Il était un petit navire” is the hit Megan teaches the Draperinos. Clearly, it passes the one truth test of all Western kids’ songs by being either about Jesus or about death.
In my family, we were content with “Frère Jacques” in the chansons françaises department. Occasionally we would talk our mom into singing us “Il est né le divin enfant,” but we had trouble learning the words on our own.
