Elsa Leroy was "Miss Mademoiselle Age Tendre" 1965. The French teen magazine used to choose a new Miss every year. And most of the time, the winner tried to become a pop singer. In 1966 she had a small role in Jean-Luc Godards film "Masculine Feminine" as "Miss 19". She has the typical Yé-yé girl story: Met her husband and dissapeared leaving us 1 excellent EP of pure yéyé goodness.
The guitar riff in "Comment Fais-tu" reminds me a lot of The Who's 'My Generation', which seems to be the most typical song for inspiration of yeye songs in the mid-60s. I haven't seen this song posted on other blogs, so I hope you will enjoy it! "Comment Fais-tu", along with her 3 other ones, are featured on Sixties Girls 5 available on Magic Records.
