Those who have turned on a television or radio in Argentina would not ask why a biography of Hector Larrea is a necessity. In a career as long as certain South American rivers of repute he has been featured as the upfront vocalist of his own band, as an actor, and as an MC on many popular broadcasts. Nonetheless, the "why" word will come up not once but three times, at the heart of one of Larrea's thrusts into the international pop scene. In the second half of the '40s, American record companies and music publishers were looking toward Latin America for hit song material. Songwriter Osvaldo Farres Vazquez, a fellow Argentinian, came up with a probing ditty circa 1947 entitled "Quizas, Quizas, Quizas": why, why, why?
Larrea was leading his outfit Hector y Su Gran Orqu. de Jazz at the time and quickly found a reason to jump on the song, as did local competitor Rene Cospito y Su Ritmo. Meanwhile radios were conducting an inquisition around the globe. In France it was "Qui Sait, Qui Sait, Qui Sait" while British folks seemed on the verge of an answer with "Perhaps, Perhaps, Perhaps." Larrea's laurels were not rested on: he quickly moved on to what, where, and who, becoming increasingly comfortable with the role of MC on programs such as Viernes de Esco and Rapidisimo, often featuring talented Latin performers. Larrea was indeed extremely supportive of the younger generations of singers such as Maria Grana, whom he presented repeatedly.
