Otelo Saraiva de Carvalho, the chief strategist of the military coup by the Armed Forces Movement (MFA), needed a signal that could be transmitted nationwide via radio to all the military officers of the MFA, to indicate the start of their operation. His initial idea was to transmit Afonso's song "Venham Mais Cinco", but João Paulo Diniz, a radio host from who took part in the plan, convinced Saraiva de Carvalho that it was not good idea since the song was forbidden by censors and that would raise suspicion.
