KAJ becomes the new advertising pillar for the classic Finnish alcoholic drink Hartwalls Original Long Drink in Sweden. The humor trio will be seen in their marketing, where connections are made to the word "bastubröder", according to Resumé, which has taken part of the advertising materials.
As participants in Melodifestivalen, KAJ can do advertising as long as it does not allude to their participation in the competition. And the song "Bara bada bastu" cannot be used for 30 days after the competition. Otherwise, it's free to go, states Anders Wistbacka on SVT.
Spontaneously, I would say that it doesn't cross any border. They have the right to do advertising. And yes, there is sauna in the song, absolutely. But there is a lot of sauna in Finland too, he says to Resumé.
I need to check with our lawyers, but based on what you're saying here and now, it doesn't sound like it's crossing the border.
