Jérémie Renier trained for months to learn how to dance and sing like François.
After a break-up with singer France Gall in 1967, he was very depressed. In order to help, Jacques Revaux, a friend of his, proposed him a little melody. With Revaux and Gilles Thibaut, he wrote the lyrics about a failing couple, destroyed by their usual life habits. It was titled "Comme d'habitude". A little time later, the song had an English version: "My Way".
