This is the strongest case in the corpus. An educational publication from the Johnny Mercer Foundation states that the French song did not become a hit until Johnny Mercer's English lyric appeared in 1950. It then became a worldwide hit, an American standard and a song recorded more than a thousand times.
The sequence closely matches the logic of Jewish Songs. In English.:
the melody already had strength;
the cultural value already existed;
the English lyric opened a new performing and market life;
Paul Anka acquired the rights to the French melody and deliberately refused to translate the original story. He wrote in the voice and image of one specific performer. The Canadian Songwriters Hall of Fame records the outcome: the song became one of the most recognizable in the world, became Sinatra's signature and spent a record 124 weeks on the United Kingdom chart.
The lesson is not that meaning should always change. It is that adaptation must answer to a target voice and target audience. A song for everyone is often written very precisely for someone first.
Jack Lawrence created an English-language love story on the French melody. Bobby Darin made it an energetic personal standard, and Official Charts records a United Kingdom peak of number eight. The role of arrangement is especially visible here. An accessible lyric without a new performing identity would not explain the recording's durability.
Rod McKuen's English adaptation, followed by Terry Jacks's softer pop treatment, changed the emotional mode of the song. Official Charts records four weeks at number one in the United Kingdom. A target market often adopts not a philologically exact document, but an independent song that works in its own emotional grammar.
The English version became a standard through the Everly Brothers, whose voices and close harmonies made the lyric feel like a natural extension of their artistic identity. Its number-thirteen peak at Official Charts is less dramatic than other cases, but the durability of later covers shows another form of success: the song became welcoming to future performers.
