The DMGP was held at the Tivoli in Copenhagen, hosted by Jørgen Mylius. Ten songs took part with the winner being decided by voting from five regional juries. Firstly the five lowest-placed songs were eliminated without full voting being revealed, then the remaining five were voted on again to give the winner. Other participants included past and future Danish representatives Dario Campeotto, Tommy Seebach, Birthe Kjær and Kirsten Siggaard of Hot Eyes.
On the night of the final Herdorf performed 19th in the running order, following Finland and preceding eventual contest winners Ireland. "En lille melodi" had been viewed as the kind of safe, unadventurous Eurovision song unlikely to be challenging for the win, but likely to pick up a lot of mid-range points and perform relatively well overall. At the close of voting the song had received 83 points, placing Denmark joint 5th (with the Netherlands) of the 22 entries. The Danish jury awarded its 12 points to Germany.
