The Norwegian participating broadcaster, Norsk rikskringkasting (NRK), selected its entry through the Melodi Grand Prix 1977.
[2] Norsk rikskringkasting (NRK) opened a submission period for entries which lasted from 16 November 1976 until 10 December 1976.
All four entries were recorded by either Ellen Margrethe Johansen or Helge Nilsen and were arranged by Brødrene Thue.
[18][21][26] All four entries were recorded by either Hans Petter Hansen or Magne Høyland and were arranged by Håkon Berge.
[12][27] On the night of the final Skorgan performed 5th in the running order, following Austria and preceding Germany.
At the close of voting "Casanova" had picked up only 18 points, placing Norway joint 14th (with Portugal) of the 18 entries.
[29] On the night of the broadcast, many viewers wondered why they were merely shown panning shots over the audience in between the songs, rather than the postcard-style clips of the next performers which had become traditional in the 1970s.
It later transpired that the planned postcards had been filmed by the BBC during a night out for all the performers at a London nightclub, but when they were previewed NRK had objected as in several of the clips Skorgan could be seen drinking alcohol – at 18 years old she was below the age for legal alcohol consumption in Norway (although not in the United Kingdom) – and behaving in a manner which NRK deemed inappropriate.
