A YouTube video for the song, Rise Again, shows Northug training ceaselessly to get back into form, accompanied by soaring vocals from Jacob Øyre Gundersen, who goes by the stage name Jack Taylor.
The song also features Utøya survivor Mohamed ‘Mo’ Abdi Farah, who reached the semi-final of Norway’s 2014 Melodi Grand Prix with the song Heal, but was beaten to the Eurovision contest in Copenhagen by Carl Espen’s Silent Storm.
Northug vies with 1990s legend Bjørn Dæhlie for the title of the most successful World Champion skier in history, but left last year's Winter Olympics in Sochi without a medal.
