Early in his career Kalvik found success putting music to the poetry of popular Norwegian writers André Bjerke and Inger Hagerup.
[1] His first four albums reached top 15 on the Norwegian record charts: Tusenfryd og grå hverdag (1971), Finn (1972), Nøkkelen ligger under matta (1974) and Fyll mine seil (1976).
[1] One of the songs on Natt og dag was "Aldri i livet" (Never in my life), with which Kalvik won the Norwegian Melodi Grand Prix in 1981.
The song was still a big success in Norway, and was even recorded in English as "Here in My Heart" with lyrics by Ralph McTell and backing vocals by ABBA's Agnetha Fältskog and Annifrid Lyngstad.
The segment caused mental distress for Kalvik, and the jokesters Harald Eia and Bård Tufte Johansen had to apologize publicly (via the show's producer, Lars Hognestad).
