Bryllup pĂĄ Haugseter = Wedding at Haugseter (Haugseter is a place, this one is quite typical Norwegian wedding "march" thing... Old style.)
Savn = Longing, or the feeling of longing
Thisledew = an obvious non-Norwegian word XD
Varganatt = Wolf's Night ("varg" is an old word for wolf, now we use "ulv")
