Poland planned start in ESC 1975?

[Poland]

How do you think it could be true that Edyta Górniak could not be the first Polish representative at Eurovision? I mean that TP, the former incarnation of TVP, could have considered the start of my country in 1975.

According to legendary rumors, Anna Jantar was supposed to represent us in this debut with the song entitled "Mój, tylko mój (Mine, only mine)" but in the end TP had to recognize the superiority of the broadcaster from Yugoslavia (debut in ESC 1961 but communist with my country) which the EBU chose instead of Poland.

What do you mean the EBU 'chose' Yugoslavia instead of Poland. Yugoslavia wasn't part of the Warsaw Pact so they were free to participate in a contest with "Western" European countries.
