She was born in French-speaking Belgium as Claudine Luypaerts, but like a few other Belgian artists, changed her name and found fame in France.
"Toutes Les Mamas", from 1989, is my favourite song of hers. I like "Danser" too. She may not have had traditional pop star looks - I always thought she was a bit 'mumsy' - but there's no doubt that her jazzy and distinctive voice put her well ahead of many of her contemporaries.
