The final was held at the Typhon Hall in Turku, hosted by Kati Bergman. Ten songs took part with the winner chosen by an "expert" jury. Other participants included former Finnish representatives Riki Sorsa (1981) and Kirka (1984).
On the night of the final Kärkinen performed 16th in the running order, following Israel and preceding Germany. "Hullu yö" was the only rock-influenced song in the 1991 contest, but went largely unappreciated by the national juries as at the close of voting it had received only 6 points (4 from Ireland and 1 each from Greece and Iceland), placing Finland 20th of the 22 entries. The Finnish jury awarded its 12 points to Italy.
