The fourteenth annual Eurovision Song Contest broadcast from Teatro Real in Madrid, Spain.
At this point in Eurovision history no one had prepared for the possibility of a tie for first place, let alone a four-way tie. The result was that France, the Netherlands, Spain and the United Kingdom were all crowned champions. This caused a hiccup in the medal giving ceremony because there were not enough to go around, and the songwriters did not receive theirs until later.
The winning entries were France's Frida Boccara singing "Un jour, un enfant", the Netherlands' Lenny Kuhr with "De troubadour", the UK's Lulu with "Boom Bang a Bang" and Spain's Salome singing "Vivo cantando".
If current rules (which award first place to the country with the most high votes) had been in place, France would have been the overall winner, followed by Spain, the UK and then the Netherlands in fourth.
