'A force de prier' was Nana Mouskouri's Eurovision entry for Luxembourg back in 1963. According to her: "It was a beautiful song, but when I listened to the other participants, I understood that I would not win". It must have been a disappointment to land on 8th place. It has to be said that the winning song, 'Dansevise' was a true classic, but this song should at least have been in the top 5.
