"Dominique" is a popular song in French by Soeur Sourire, the Singing Nun from Belgium, about Saint Dominic and his fight against the Albigensians. The song was co-written with Noel Regney.
A remarkable fact is that the song reached and stayed at #1 on both the U.S. pop chart and "easy listening chart" (since renamed the Adult Contemporary chart) for four weeks in December of 1963.
The artist who performed it, Jeanine Deckers, never again reached the same success and continued to lead a colourful, but tragic life. She and her lesbian girlfriend, Annie Pescher, both committed suicide in 1985.
