Mammola Sandon, known by the stage name of Flo Sandon's (29 June 1924 – 17 November 2006), was an Italian singer who was popular in the post-World War II years. She won the Sanremo Music Festival in 1953 with the song "Viale d'autunno".
Sandon was born in Vicenza, in the Veneto. Her musical career began in 1944 when she debuted in a Red Cross charity show. Her stage name Sandon's came by chance - it was an oversight by the illustrator who prepared her first record cover. Her first big break as a professional vocalist came in 1947, when she sang in The Hot Club of France with two jazz legends: guitarist Django Reinhardt, and violinist Stéphane Grappelli. Celebrity came in 1952 thanks to the movie Anna directed by Alberto Lattuada and starring Silvana Mangano, Vittorio Gassman and Raf Vallone. Flo Sandon's did not appear in the movie itself, but she performed two songs on the movie soundtrack, "T'ho voluto ben" and "El negro Zumbon". Both were great hits. Nat King Cole liked "T'ho voluto ben" so much that a few years later he recorded it with the new title "Non Dimenticar".
