The song was adapted into Norwegian by Lillebjørn Nilsen as "Barn av regnbuen" (which in English means "Children of the Rainbow").
The song was performed by Nilsen and a crowd of more than 40,000 people in Youngstorget in Oslo and at squares across the country on April 26, 2012, as a protest against statements given in court by Anders Behring Breivik, the perpetrator of the July 22 attacks in 2011.
The performance was inspired by Facebook reactions after Breivik claimed in his trial testimony that the song was an example of Marxist propaganda and that it was being used to "brainwash" Norwegian children.
"[4] Psychiatrist Thor Kvakkestad criticized this public outpouring of emotions during an ongoing trial and called for a focused discussion about the hate that seems to be building in the Norwegian populace.
[5] The song was performed by delegates attending the 2012 ECOSY Summer Camp held in Croatia in July and a music video on YouTube was recorded in support of the victims of the attacks in Norway.
