Nicoletta Grisoni, longer name Nicole Fernande Grisoni-Chappuis, better known by her mononym Nicoletta (born 11 April 1944 in Vongy, now known as Thonon-les-Bains, Haute-Savoie, France) is a French pop singer. Becoming very popular on French radio and television, where she had a number of hits in the 1960s and the 1970s, she was considered as part of what is known as the French yé-yé generation heavily influenced by American music, particularly Rhythm and blues, Rock and roll and Beat music. She is mostly known for her version of "Mamy Blue".
