Cabral continued to achieve success with various compositions, including "Teus Ciúmes" with Laci Martins, "Amigo Leal" with Lacerda, and "A Você" with Ataulfo Alves.

In 1939, Cabral co-wrote the samba-exaltação "Brasil" with Lacerda, recorded by Francisco Alves and Dalva de Oliveira, marking one of his most significant successes. His work extended to the theater, where he contributed to musical revues, and he was active in radio production.

Throughout his career, Cabral's compositions were recorded by prominent artists such as Orlando Silva, Francisco Alves, and Carlos Galhardo, cementing his legacy in Brazilian music. He passed away on June 5, 1994, in his hometown of Rio de Janeiro, leaving behind a rich repertoire of music that continues to be celebrated.
