There is an unusual link to the Euro-vision Song Contest and this revolution. Portugal may never have won the contest until 2016 but they sure did use it to great effect in 1974… See below an interesting fact I found in my research.
The pictures below were sent to me by a friend in Lisbon, Manuel Luis Cochofel, who also alerted me to the history of this square.
Remarkable: There were two secret signals in the military coup: first the airing of the song “E depois do adeus” (“And after the farewell”) by Paulo de Carvalho, Portugal’s entry in the 6th of April 1974 Eurovision Song Contest, which alerted the rebel captains and soldiers to begin the coup.
Next, on April 25, 1974 at 12:15 am, the national radio broadcast played a song by Zeca Afonso, a progressive folk singer forbidden on Portuguese radio at the time. This was the signal that the MFA revolutionaries gave to the citizens to take over strategic points of power in the country and “announced” that the revolution had started. The revolution culminated in
