Tenn Lys is a song for Advent written by Eyvind Skeie and Sigvald Tveit for the TV-series “Portveien 2”. The song follows the Norwegian tradition of lighting a candle for each of the four Sundays in Advent, with a verse of the song for each of the four candles. “Tenn Lys” has quickly become an established part of the Norwegian Christmas season.
