Never cared much for her singing... Give me Barbara, Juliette Greco, Jacques Brel, Gainsbourg, etc any time and keep Piaf!
Saw her several times - including a show in the late 40s at the Paris ABC theater where she appeared on the same bill as Yves Montand and Les Compagnons de la Chanson - and thought she was quite unattractive. Also saw her near the end of her life with her companion Theo Sarapo. They were a pitiful sight!
