One of their greatest hits was the song "Senhora Liberdade", which became an anthem in the Brazilian Diretas movement for the institution of direct national elections in the 1980s.
Some other famous songs from the duo are "Gotas de Veneno", "Sandália Amarela" and the non-samba "Candongueiro", which brings forward their African roots, with other successes as, e.g., "Meu Apelo", being signed by Wilson alone.
Brazilian virtuoso Raphael Rabello was a big fan of Wilson, and took part in his records Peso na Balança and Okolofé, both of which are considered up to this day some of the best finished samba albums ever.
[citation needed] In March 1997 Wilson Moreira fell victim to a stroke which left him partially immobilized.
Fund-raising shows were organized by the samba scene in order to obtain more resources for better treatments to the sambista.
