That same year he was invited by Vinicius de Moraes, co-writer of the worldwide hit "Garota de Ipanema" (The Girl from Ipanema), to participate in a series of shows in Buenos Aires, forming a solid partnership that would continue for 11 years and produce 120 songs, 25 records and over a thousand shows. After the death of Vinicius de Moraes in 1980, Toquinho went on to pursue a solo career, often performing with other talented musicians like Paulinho da Viola, Danilo Caymmi, Paulinho Nogueira and Chico Buarque.
