"Se ilden lyse" (in English: "Fire in Your Heart") is a single by Norwegian singer Sissel Kyrkjebø, released as the official song of the 1994 Winter Olympics in Lillehammer, Norway.

The duet between Sissel and Plácido Domingo, Fire in Your Heart, was recorded in a canteen in Lillehammer before the opening of the 1994 Winter Olympics.

Because of the tight schedules of both Plácido Domingo and Sissel, they had only a few hours to record this English version of the Olympics anthem before the opening ceremony.

He asked us to send her complete portfolio to L.A., but due to the terrible earthquake the mail arrived too late, so we didn't get an answer in time.

A few hours before the opening ceremony he recorded his part in an improvised mobile studio, from where he had to rush back to Spain, but not after inviting her for a guest slot on his upcoming album.
