Grândola, Vila Morena - Portuguese Carnation Revolution Song

Grândola, Vila Morena" (English: Grândola, Brown Town) is a Portuguese song by singer-songwriter José Afonso, recorded in 1971. It was originally released in Afonso's 1971 album Cantigas do Maio and later released in an EP of the same name in 1973, and as a single in 1977.
"Grândola, Vila Morena" became an iconic song in Portugal after being used as a radio-broadcast signal by the Portuguese Armed Forces Movement during their military coup operation on the morning of 25 April 1974, which led to the Carnation Revolution and the transition to democracy in Portugal. It has since been considered a symbol of the revolution and anti-fascism
