Torr was part of the Yé-yé generation, a singer under 20 years of age singing mostly uptempo songs. Other famous yé-yé singers were France Gall, Françoise Hardy and Sylvie Vartan. A 19 year old Torr gave a confident performance in the 1966 edition of Eurovision Song Contest representing the host country Luxembourg.
I find her performance and the song one of the best in the 1966 contest, which was not of the highest quality contests in the 1960's. The result, 10th place among 18 participant was surprising and disappointing. I still like the song even though it hasn't aged as well as some other entries from the 1960's.
Michèle Torr was already a star and she returned to the Eurovision Stage in 1977 representing Monaco with a song Une petite française, which she preferred to her 1966 entry and which improved her result finishing fourth. She is still continuing her career performing regularly and releasing new material occasionally.
My points 3/5.
