From the wiki: “‘Beyond the Sea’ is the English adaptation of a romantic love song (‘La Mer’, ‘The Sea’) popularized in 1946 by French singer Charles Trenet, most famous for his recordings from the late 1930s until the mid-1950s. In an era in which it was unusual for a singer to write their own material, Trenet wrote prolifically and declined to record any but his own songs.
“According to legend, ‘La Mer’ was composed by Trenent on-board a train in 1943 as he was gazing out of the window at the Étang de Thau, a lagoon in the south of France. He jotted it down on a piece of paper and in the afternoon he worked out the details with his pianist Léo Chauliac. That evening they performed it in front of an audience without much of an impact. Trenet explained in an interview that he was told that ‘La Mer’ was not ‘swing’ enough to be a hit, and for this reason the song then sat in a drawer for two years before being recorded for the first time in 1945 by Roland Gerbeau. Trenet would record a cover of his own song also in 1946.
