[3][7] Due in part to the economic conditions in post-war France, Lux had difficulty finding buyers for his songs.

[6][8][5][3] In the 1940s, he ran a hardware store in Asnières-sur-Seine, where he would set up games for his customers to play, especially during the Tour de France.

This show would later become La roue tourne, which he hosted alongside Jean-Francois Chiappe and Marina Gray in 1960-1964.

[5][3] Another significant game show he hosted was Intervilles in 1962-1964, 1970-1971, 1973, and 1985-1991, almost the entire time with Léon Zitrone, Simone Garnier, and Claude Savarit.

[14][15][3] Sophie Darel, with whom he worked for 15 years on a number of shows, described him as "very anxious" and angry because of it, though she still had affection for him since his violent outbursts lasted only briefly.

[4] Christiane died in a car accident in 1964 and Lux and his wife raised her 3-month old son, Jean-Christophe Lauduique, in her place.

[4] Jean-Christophe and actress Ariane Séguillon are parents to Dorian Lauduique of the French DJ duo Ofenbach.
