Trivia

In a break from the tradition that the contest is hosted by the previous year's winners, it was held in the United Kingdom, who had finished 4th, rather than France, who had won in 1962, because they had already hosted the 1959 and 1961 edition and declined to host a third time the competition in such a short time. It was the second time such thing happened. The United Kingdom had already hosted the 1960 edition after The Netherlands winning in 1959, for the same reason, The Netherlands declined because they had already hosted the 1958 edition.

Differently from other years, where the contest was broadcast from a theater or auditorium in front of a live audience, this contest was done in the BBC Television Center in London, inside three TV studios, one for the host, audience and scoreboard, another one for the artist, and a third one for the orchestra. Live audience watched the performances from TV screens in their studio.

As the live audience watched the performances from TV screens, there were accusations that the performances were pre-recorded earlier in the day using lip-sync as microphones were not visible. Against these accusations, it was noted that boom microphones were used, something possible since the contest was being done in a TV studio.
