The duo Elisabeth "Bettan" Andreassen and Hanne Krogh have written the text and music to the entry themselves.
The Norwegian Melodifestivalen takes place on February 15. It will be the start of a jubilee celebration for the group in Norway with concerts in Oslo in May and a nationwide tour in the autumn.
The Swedish-Norwegian Elisabeth Andreassen and Hanne Krogh took Norway's first victory in the Eurovision Song Contest, when they won the competition in Gothenburg 1985 with the song "La det swinge".
The duo broke up in 1988, but have reunited on various occasions for individual performances.
