Norsk rikskringkasting (NRK) held the Melodi Grand Prix 1971 on 20 February at its studios in Oslo, hosted by Jan Voigt.

Other participants included past and future Norwegian representatives Inger Jacobsen, Odd Børre, and Anne-Karine Strøm.

Lyrically, "Lykken er" (translated as "Happiness Is") was little more than a list of pleasant things and experiences which Krogh enjoyed, leading to much comment that it was an overly-obvious attempt to replicate the previous year's winner "All Kinds of Everything", with a good dash of "My Favourite Things" from The Sound of Music thrown in for good measure.

At MGP Krogh had performed in normal teenage attire, but in Dublin she sang dressed in a Victorian gown, complete with a parasol which she opened, closed and twirled throughout the song.

[2] The poor result was largely attributed to the fact that the whole package of song, performance and presentation was much too cute, precious and twee for its own good, and was likely to have left a negative impression with the voters.
