He was born Guy Béhart-Hasson in Cairo, Egypt, of Spanish, Swiss, and Russian ancestry. His father’s work as an accountant and business consultant saw the family move frequently, leading to a childhood spent in France, Greece, and Mexico, in addition to Egypt. Between the ages of 10 and 17 his family settled in Lebanon where his interest in music developed to the point that he left for Paris to study at the “École nationale de musique”. In addition to music, he also obtained a degree in engineering.

When his father died in 1952, the young Guy Béhar chose to pursue a career in engineering in order to help support his family, studying at the prestigious École Nationale des Ponts et Chaussées. Simultaneously, however, he enrolled in Paris’s École nationale de musique, studying violin and mandolin, and in his spare time wrote songs and worked the Paris cabaret circuit, where he played guitar and sang under the stage name “Guy Béart”. When a version of one of his songs by a popular performer of the day became a huge success, demand for his writing talents increased and he composed for Juliette Gréco and others. Taken under the wing of renowned music producer Jacques Canetti and fellow musician Boris Vian, he released an album of his own, which won the prestigious Grand Prix de l’Académie du Disque français in 1958.

Normally shy, Béart initially suffered from stage fright and had a very difficult time during his concert debut at the Paris Olympia. His biggest hit came when he wrote the soundtrack of the 1960 motion picture, Girl and the River. The title song of the film is considered a classic of what is known as French chanson. Despite his leap to fame, Béart’s singing career was soon swamped by the rising tide of American rock and roll. However, reinventing himself as a host of a television show featuring musical stars from a variety of genres, he remained in the public eye and eventually made a recording comeback.

In 1963 he and his wife, Geneviève Galea, had a daughter, Emmanuelle, who would grow up to be an actress.

After Béart’s television show ended in 1970, his popularity waned but he continued to record new music that was readily purchased by a loyal following. By the early 1980s he was almost completely out of the spotlight and, although only in his early fifties, he suffered from a number of serious health problems. In 1987, he published a book about his illness entitled Crazy Hope that, combined with his daughter’s success in the blockbuster film Manon of the Spring, brought a resurgence of popularity. More than 25 years after his first appearance at the Paris Olympia, he returned for a series of highly successful performances.

In 1994 Béart was awarded the Grand Prix de l’Académie française in recognition of his achievements over his long career. He continued to perform at a variety of venues around the country and in 1999 did a five-week run at Bobino in Montparnasse that was so popular it allowed for a successful re-release of his double live album recorded at the Olympia.

Now, well into his seventies, he only makes a rare appearance on stage but many of his songs, of which Béart wrote more than 300 himself, are still being purchased by his fans.
