Catchy as hell.
Les Djinns (choir) - Wikipedia
Several of Les Djinn Singers graduates continued on with separate recording careers. In September 1962, Les Djinn' lead soloist Annie Markan and three other members of the group – Graziella, Michèle and Suzie – formed the vocal quartet Les Gam's. (The name was derived from the first letter of each girl's name plus the added apostrophe to add a fashionable touch.)
