Portuguese singer-songwriter José Afonso was inspired to write his song "Grândola, Vila Morena" after performing in Grândola on 17 May 1964. "Grândola, Vila Morena", first recorded in 1971, became an iconic song in Portugal after being used as a radio-broadcast signal by the Portuguese Armed Forces Movement during the 1974 Portuguese coup d'état, which led to the Carnation Revolution and the transition to democracy in Portugal.[5]
