It took place in Copenhagen, Denmark, following the country's victory at the 1963 contest with the song "Dansevise" by Grethe and Jørgen Ingmann.

The winner of the contest was Italy with the song "Non ho l'età", performed by Gigliola Cinquetti, written by Nicola Salerno and composed by Mario Panzeri.

Poul Leth Sørensen served as producer, Bent Fabricius Bjerre and Marianne Drewes acted as co-producers.

[12] A political protest occurred after the Swiss entry: a man trespassed onto the stage holding a banner that read "Boycott Franco & Salazar".

[13][14] The interval act consisted of a ballet dance performance by dancers Solveig Østergaard, Niels Kehlet, Inge Olafsen and Mette Hønningen from the Royal Danish Ballet, choreographed by Niels Bjørn Larsen, and over the music of the "Columbine porka mazurka" and the "Champagne Galop" by Hans Christian Lumbye.

[15] The immediate response of the Koncertsal audience to the Italian entry was markedly enthusiastic and prolonged and, most unusually for a contest performance, after leaving the stage Gigliola Cinquetti was allowed to return to take a second bow.

Broadcasters were able to send commentators to provide coverage of the contest in their own native language and to relay information about the artists and songs to their television viewers.

Some clips of the contest have survived, including the winning announcement by Svend Pedersen, and part of Gigliola Cinquetti's reprise.

In a 2019 interview, DR claimed that the broadcast was never recorded in the first place, allegedly due to no tape machines being available at the studio at the time.

[55] The audio of most of the show, however, is still available online, without the last few minutes, and short video clips and photos from various archives also remain available.
