It's Danish :D Nicely sung indeed. One should add that this song is the 3rd of a cycle called "Hjertets Melodier" (Melodies of the Heart). I've sung the 1st one "To brune Øjne" (Two Brown Eyes) in my language.
it's sung in danish same spelling as older norwegian but very different accent - very nice - listen to flagstad in norwegian. not sure why everybody sings it twice. original only one time
@@jorgeferrari2437 Quite right, but Swedish, Danish and Norwegian are linguistically speaking closely related dialects, easily mutually intelligible. The Scandinavians usually speak their own language with each other.
