Søren later decided to leave Sir Henry in favor of further cooperation with Kirsten, and the duo entered the Dansk MGP in 1984 as Hot Eyes with the song "Det' lige det" with music by Søren and lyrics by Keld Heick (who also penned lyrics to all other Hot Eyes' Dansk MGP entries). The song became known in Denmark as the "swimming pool song", as at the end of the Dansk MGP performance Kirsten threw Søren into a swimming pool by the stage. They won the contest and therefore represented Denmark at the Eurovision Song Contest 1984, taking the fourth place, even though they were unable to replicate the swimming pool gimmick. This was Denmark's best placing since 1963, when the country's entry won the contest. Kirsten was actually pregnant with her first son while singing at Eurovision.
