Waschko, Roman (1980-09-06). „Finn Singer Triumphant At Sopot Contest”. Billboard. Nielsen Business Media. стр. 65. Приступљено 2011-04-05. „Two competitions were held at the 4th Intervision Song Festival in Sopot August 20–23, 1980: one for artists representing television companies, the other for those representing record companies. In the first the jury considered the artistic merits of the songs entered; while the performers' interpretation was judged in the second. The outcome was a victory for Finnish singer Marion in the first contest, "Where Is the Love?" taking the Grand Prix. Six year ago, the same artist won Grand Prix at the Sopot International Song Festival. First prize was shared by Czech performer, Marika Gombitová with "Declaration", and Russian Nikolai Gnatiuk for the song "Dance on a Drum".”(језик: енглески)
