The Eurovision Song Contest 1964 was the ninth edition of the contest, organised by Danmarks Radio (DR) and held on 21 March 1964 at the Tivoli Concert Hall in Copenhagen, Denmark. Sweden were forced to withdraw due to industrial action by the Swedish Musicians' Union, however as made its debut appearance the total number of competing countries remained at 16. Another modification of the voting system now saw each country giving 5, 3 and 1 points to the top 3 songs based on the total of all votes cast by jury members, with each jury member having three votes to distribute among the songs; if all members voted for only two songs, these would get 6 and 3 points, and if all members voted for the same song it would get 9 points. This event marked the first time that the contest was interrupted by a protester, when a man demonstrating against the right-wing dictatorships of Spain and Portugal and the inclusion of these countries in the contest entered the stage holding a banner stating "Boycott Franco and Salazar", before being quickly removed as cameras cut to a shot of the scoreboard. No footage of this protest remains however as, like the 1956 contest, no video of the contest is known to exist, bar short footage of the opening sequence and the winning reprise, while audio recording are known to survive. Italy's Gigliola Cinquetti scored a landslide victory with the song "Non ho l'età", gaining almost three times as many points as the United Kingdom in second place and giving Italy its first Eurovision win.
