Portrait of Charles Trenet. Twenty years after his death, this documentary offers a new look at the artist. When, in 1956, the singer appeared on television, he was 43 years old. And it is a man of 60 or even 70 years old that today's audience has known. The first Charles Trenet, the one who transported France when he was 25 or 30 years old, remains largely unknown. Yet it was this kid of genius who, at the age of 25, invented French chanson. But the archives that are scattered throughout this portrait also show that he invented a certain idea of joy. For joy in Trenet was a sport, a daily gymnastics.
