The 1964 Eurovision Song Contest took place in the famous Tivoli Concert Hall in Copenhagen. The event became highly politicised with demands that right-wing dictatorships in Spain and Portugal should be excluded from the contest. There was even some trouble during the contest as just before the Belgian entry, a man entered the stage holding a banner saying "Boycott Franco and Salazar". He was quickly removed from the stage. As in the three previous contests, 16 countries participated in the competition. Portugal made its debut whilst Sweden chose not to enter. Germany, Portugal and Switzerland each scored zero points for the first time. In the case of Portugal, it was the first time in the history of the contest that a newcomer did not receive any points at all.
