The MGP was held at the studios of the Norwegian Broadcasting Corporation in Oslo, hosted by Odd Grythe. Five songs took part in the final with each song sung twice by different singers, once with a small combo and once with a full orchestra. However Wenche Myhre, who had been due to perform a version of "Karusell", had to withdraw at the last minute through illness so Sparboe sang both versions of the song. The winning song was chosen by postcard voting.
On the night of the final Sparboe performed 7th in the running order, following Austria and preceding Belgium. Each national jury awarded 5-3-1 to their top three songs, and at the close "Karusell" had picked up only 1 point (from Austria), placing Norway joint 13th (with Portugal) of the 18 entries. The Norwegian jury awarded its 5 points to the Netherlands.
