From Discogs: Isabelle Morizet, french disco - pop singer, active from mid-70's to early 90's.
First known as Carène Chéryl with romantic songs, her pseudonym was changed to Karen Cheryl at late 70's when she turned to more disco tunes.
She has now stopped her carrer, abandoned her pseudonym for her real name and has now her own programme on a national radio station. We can also see her on french TV "France 3".
