The song was performed sixteenth on the night (following Israel's Duo Datz with "Kan" and preceding Germany's Atlantis 2000 with "Dieser Traum Darf Niemals Sterben"). At the close of voting, it had received 6 points, placing 20th in a field of 22. It was succeeded as Finnish representative at the 1992 Contest by Pave Maijanen with "Yamma, yamma". This song can be found on Kaija Kärkinen's 1991 album Mustaa vettä.
