There is a magical moment in François Truffaut’s 1962 film Jules et Jim when the  breathtaking Jeanne Moreau sings a French folk song — Le Tourbillon” (“The Whirlwind”) — to her two male companions. Unable to decide between the two men (played by Oskar Werner and Henri Serre), she sings this song about emotional turbulence.

It became a popular hit in France. But I warn you: Once heard, it takes up permanent residence  in your head and will be heard in perpetuity.

Absolutely joyful.
