The song "Que nadie sepa mi sufrir" ("Let no one know my suffering"), was composed in 1936 by Ángel Cabral, with (Spanish) lyrics by Enrique Dizeo, both of Argentine origin. It was a Peruvian Vals, which, in the period between the 1930s and 1950s, was a very popular musical genre in Spanish-speaking America. The song became a regional hit.
Almost twenty years later, during a Latin American concert tour, Edith Piaf heard it from the 1953 recording by Alberto Castillo. Piaf recorded a French language version, with lyrics by Michel Rivgauche, which became a hit itself. Subsequently, the original song was a hit once more, under the title "Amor de mis amores" ("Love of my loves"), the first verse of the chorus in the Spanish version.
The rhythm respects the 3/4 of the regular Waltz, but, as a Peruvian Waltz, requires a light step and a much faster tempo.
Michel Rivgauche's lyrics relate the chance meeting between the singer and a man in the middle of a dense and festive crowd. It's love at first sight, at least from the singer's part, who thanks the crowd for giving her this man. But, just as quickly as it brought them together, the crowd separates them and she never sees him again. "The crowd appears as a sort of demiurge (creator), like destiny, playing with the human beings who are helpless against the vagaries of chance."
