“Dominique” – The Singing Nun (French – December 7, 1963, For Four Weeks)
Dominique was a massive success in 1963, a few months after Sukiyaki. Jeannine Deckers, the Belgian nun with fantastic French, sung the song about Saint Dominic, the founder of the Dominican order, of which she was a part.

A lot of people claim that the song only became a massive hit because radio DJs wanted to play something with pleasing music after President John F. Kennedy got assassinated. After owning a lot of taxes to the Belgian Government, and after going broke, Jeannine tried to release a disco version of the song, which was as big a failure as the original one was a success.
