A lejlighedssang (English translation: Occasion song) is the Danish term for a genre of homemade novelty song or ballad written and sung for a special occasion. The lejlihedssang is a traditional part of family celebrations, particularly during confirmation, wedding and anniversary parties. Participants write lyrics for the specific occasion composed upon a popular tune. Copies of the lyrics are written on decorative pages and distributed among the celebrants to be read and sung en masse. The tradition in Denmark dates back to the street ballads and political club songs of the late 1700s. Group singing became further integrated across Danish society by the influence of N. F. S. Grundtvig's national consciousness and public school movements in the mid 1800s.<ref name="Kjær"/> By post-World War II, the singing of lejlighedssang at celebrations was typical.<ref name="Kjær"/> According to Danish historians, the lejlighedssang exists in modern Danish culture as an important form of group bonding or fælleskab (English translation: togetherness).<ref name="Stolen"/><ref name="Kjær"/>
