While Sérgio and Odair dedicated themselves to studying with Monina, Mazo continued to actively support them. Utilizando suas connections, first managed to give visibility to the brothers' work in the main Rio newspapers and, little by little, paved the way for them to perform in renowned theaters in the country, such as Teatro La Paz, in Belém, and Teatro Amazonas, in Manaus.
To further increase visibility, Mazo — now also assuming the role of businessman — managed to take them to popular television programs of the time. They, already known as "Mini Geniuses", aroused curiosity about where passavam. Thus, they took to the stage of notorious programs, such as "Um Instante, Maestro", presented by the charismatic Flávio Cavalcanti, and "Lunch with the Stars", led by the emblematic couple Aírton and Lolita Rodrigues. Also were invited to the acclaimed Chacrinha program, but Monina Távora did not allow them to participate, claiming that the program was too popular!
On the same occasion, when Mazo learned that the delegation from the Ministry of Education, in Rio de Janeiro, was looking for talent early, managed to include Sérgio and Odair in the program, guaranteeing them the chance to present themselves to the minister Tarso Dutra. As a result, they both received scholarships to attend the Anglo-American College.
Shortly afterwards, the school director invited them to introduce themselves to the network supervisors who would be visiting Brazil. The concert ended up earning the Duo an invitation to join the Youth cultural exchange project For Understanding. Soon, at the age of thirteen and sixteen, they embarked — accompanied by Mazo — to the United States, where six months would pass.
