Originally recorded (as “Pout Toi”) by Dario Moreno (1957).

From the wiki: “‘Feelings’ is credited to Louis Gasté (also known as Loulou Gasté) and Brazilian singer Morris Albert, and was made famous by Albert who recorded it as a single first released in late 1974. In 1981, Gasté sued Albert for copyright infringement, claiming that ‘Feelings’ plagiarized the melody of his 1957 song ‘Pour Toi’, recorded for the soundtrack to the 1957 movie Le feu aux poudres. They now share the credits of the song.
