Just 4 Fun

Norway was represented at the Eurovision Song Contest 1991 with the song "Mrs. Thompson", performed by the supergroup Just 4 Fun, which consisted of Hanne Krogh, Eirikur Hauksson, Marianne Anthonsen and Jan Groth. Krogh had previously represented Norway in 1971 and 1985 as part of Bobbysocks, while Hauksson had previously represented Iceland in 1986 as part of ICY.

For the first and only time in Norwegian Eurovision history, the song was selected internally after the participating broadcaster, Norsk rikskringkasting (NRK), cancelled the scheduled Melodi Grand Prix 1991 due to the 140 submitted entries all being considered "unacceptable". The cancellation caused considerable uproar and controversy among songwriters and fans, which resulted in an alternative, unofficial final being held on 23 February 1991.
