The DMGP was held at the Tivoli in Copenhagen, hosted by two former Danish Eurovision representatives, the previous year's Birthe Kjær and Dario Campeotto (1961). Ten songs took part with the winner being decided by two rounds of televoting. In the first round the bottom five songs were eliminated, then the remaining five were voted on again to give the winner. Other participants included three-time Danish representative Kirsten Siggaard (of Hot Eyes) and Jørgen Olsen, the 2000 Eurovision winner.
On the night of the final Devantier performed 11th in the running order, following Israel and preceding Switzerland. The song was very much in the same uptempo pop vein which had characterised Danish Eurovision entries throughout the 1980s. At the close of voting "Hallo Hallo" had received 64 points from 13 countries, placing Denmark 8th of the 22 entries, the country's fifth consecutive top 10 finish. The Danish jury awarded its 12 points to Switzerland.
