L'oiseau et l'enfant by Marie Myriam. The 1977 Eurovision winner is still the last song in French to win the Contest. However, it turns out that there is an English language version of the song, and it can be found on this British release.
The single didn't come in a picture sleeve, unfortunately, but the track is on the B-side, and out of the many different releases of 'L'oiseau et l'enfant', this single is the only one to include this version on the B-side.
