Duncan Laurence, the Dutch performer and one of the favorites of Eurovision song contest 2019 may be excluded from the competition. This is due to the issues with his entry song called Arcade.
According to wiwibloggs, the current rules of ESC Eurovision, the contestants are supposed to present a song, which was not officially released before September 1, 2018. Below one can see the edition of Arcade presented in 2019.
Recently, Youtube users found a video, where Duncan performs the song live in June 2017. The 29-minute-long video includes five tracks, first of which is Arcade. Thus, Laurence violates the curriculum of Eurovision, which may entail disqualification. Here's the video from 2017:
Neither Eurovision 2019 representatives nor Dutch delegation have commented on the incident so far. At the same time, this particular case can be left behind, too, because it is not considered a commercial release, having only 500 views.
