In the 1970s, Moraes collaborated with Antônio Pecci Filho, a guitarist and vocalist nicknamed Toquinho, on musical and literary works. He married three women in succession: Cristina Gurjão, with whom he had a daughter, Maria; the actress Gesse Gessy; and the Argentinian Marta Rodrigues Santamaria. He toured Europe with Chico Buarque and Nara Leão, and Argentina with Dorival Caymmi and Oscar Castro-Neves. His most stable musical partnership, however, remained with Toquinho, with whom he released popular albums. Their live performances in Brazil and Europe were often conducted as intimate meetings with the public. Moraes sat onstage at a table with a checked tablecloth and a bottle of whiskey, chatting and telling amusing stories to the audience in French, English, Spanish, Italian, and Portuguese.
