On the night of the final Bray performed 7th in the running order, following Austria and preceding eventual contest winners Sweden. "Un baiser volé" had been predicted as a likely mid-table finisher, and at the close of voting had received 29 points, placing Luxembourg 14th of the 22 entries. The Luxembourgian jury awarded its 12 points to Switzerland.
