Mammola Sandon, known by the stage name of Flo Sandon's, 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".
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 Zumbón". 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".
In 1953 Flo Sandon's took part in the Sanremo Music Festival for the first time, and won. The song was "Viale d'autunno" and it was also performed by another singer, Carla Boni. Both winners were at their first appearance at the popular song contest, and succeeded ahead of the great favorite Nilla Pizzi. The press speculated about a possible plot against Pizzi: allegedly she had been originally chosen to perform "Viale d'autunno" but was then dismissed, possibly out of spite or jealousy, and the song offered to Sandon's and Boni.
Flo Sandon's competed five more times at the Sanremo Music Festival, but never won again. She however won another song contest, the Festival of Naples in 1960 with "Serenata a Mergellina".
