"Dominique" is a popular song in French by Soeur Sourire, the Singing Nun from Belgium, about St Dominic and his fight against the Albigensians. It became a worldwide hit in 1963.

It is remembered chiefly for its refrain, which went:

Dominique -nique -nique s'en allait tout simplement,
Routier, pauvre et chantant.
En tous chemins, en tous lieux,
Il ne parle que du Bon Dieu,
Il ne parle que du Bon Dieu

"Dominic travelled around simply, a poor singing traveller. On every road, in every place, he spoke only about the Good Lord, only about the Good Lord."

The lyric nique in French is an obscenity for coitus and the song was (and still is) virtually unknown in France, but reached Billboard Magazine's No. 1 list for December 7, 1963, preventing Louie, Louie by the Kingsmen from rising higher than the No. 2 spot. It is noted with some irony that in 1963, while the FBI was attempting unsuccessfully to decipher the lyrics of Louie Louie (in order to prove that broadcasting them was illegal), radio stations were broadcasting a recording of the Singing Nun clearly vocalizing the equivalent of a banned word, to little if any comment.
