The Fraternity Brothers released Passion Flower in 1957, arranging Beethoven's Für Elise into a Latin-tinged teen-pop hook. It hit in Italy the following year and spread across European markets.
In 1959 The Peanuts cut a Japanese grand-cover based on Caterina Valente's French Tout L'Amour, with lyrics by Takashi Otowa and Tetsu Mizushima and arrangement by Hiroshi Miyagawa — fixing it as the kayōkyoku / Latin-pop standard Jōnetsu no Hana, later sung on NHK Kōhaku.
A Beethoven-derived American pop tune, filtered through Valente’s French version, is redefined by The Peanuts’ twin vocals as a Japanese hit.
