Consequently to an accident, the father became disabled and the mother, a vaudevillian, decided to form an acrobatic dance group: however, only the elder sisters Alexandrina and Judith joined in under the management of Enrico Portino.
They formed the Sunday Sisters and performed in Europe, Syria and Lebanon; Catherine was too young and stayed in a boarding school in Amsterdam.
In 1935 they got to Turin, where maestro Carlo Prato, the artistic director of the local EIAR, noted them and decided to raise them as a vocal trio devoted to harmonic singing.

It was only then that the general public knew about the 1946 replacement, when Paolo Limiti invited her to the TV show Ci vediamo su RAI 1 to tell her story.
