"Mi Viejo" (My Old Man) is an iconic song by the Italian-Argentine singer-songwriter Piero De Benedictis, released in 1969 as part of his debut album, also titled "Piero." While Piero is the author of the melody and the performer, the poignant lyrics were penned by José Tcherkaski, serving as a heartfelt tribute to his own father. The song quickly became a monumental success, selling over five million copies worldwide and topping charts for an extended period. Its enduring popularity and universal theme of paternal love have led to numerous reinterpretations by diverse artists across different genres and languages, solidifying its place as a timeless classic in Latin American music and beyond.
