The interview was on the occasion of Haakon's 40th birthday today. It is called Crown Prince Haakon, the road to a Kingdom - Kronprins Haakon, veien til et kongerike.
My transcriptions of the interview that aired on NRK tonight:

There is also a link to the interview on NRK in my post, as well as a link to the GoogleTranslated version of the interview site, and the ability to click on the subtitle tab and see every thing that was said.
Haakon always comes across well in interviews, but it was kind of neat to see him stumped a couple of times.
Frederik, Victoria and Mette-Marit are also interviewed to get a broader picture.
