It consisted of recording the "Za milion godina" charity single and staging a concert held at Red Star Stadium in Belgrade on 15 June 1985, both featuring top acts of the Yugoslav rock scene.

[1]The song, entitled "Za milion godina" ("For a Million Years") was composed by Dragoljub Ilić, former leader of the hard rock band Generacija 5, and the lyrics were written by Mladen Popović,[1] who had previously written lyrics for Denis & Denis, Oliver Mandić and other acts,[2] and was, at the time, an editor of the TV show Hit meseca (Hit of the Month).

[6] Bora Đorđević and Goran Bregović, leaders of Riblja Čorba and Bijelo Dugme respectively—two most popular Yugoslav bands at the time—refused the invitation to take part in the recording sessions.

[7] It was later revealed that Đorđević's refusal may have been based, at least partly, on his wrong assumption about the project being government-initiated, unaware that individual Yugoslav musicians and music industry people started it on their own accord.

I will play day and night for free, for charity, for whatever you want, but only after they [Yugoslav authorities] lower our [musicians'] monstrous [income] taxes, after they allow us to import musical instruments, after they give us [social] apartments...

[9]However, the article published in Rock magazine in March 1985 as a companion piece to the release of "Za milion godina" stated that Bregović and Đorđević were prevented from appearing on the recording due to their respective bands' touring commitments.

The piece further announced that the two would appear at the song's performance on the Hit meseca TV show alongside Bijelo Dugme vocalist Mladen Vojičić "Tifa".

[7] Dragoljub Ilić stated in an interview that Branimir "Džoni" Štulić, leader of the highly popular band Azra, was not considered for the song recording because he had already moved abroad to the Netherlands.

[8] In an October 1985 interview for Džuboks magazine, Zabranjeno Pušenje frontman Nele Karajlić was asked about his absence from YU Rock Misija several months earlier.

[14] The following acts played the show, in the order of appearance:[14] Marked by uncooperative weather and technical issues, the eight-hour concert was broadcast live on Radio Television of Belgrade.

[15] In a mid-2000s interview for Rockovnik, Hit meseca's host and producer Dubravka Marković talked about the weather and logistical issues during the live show: We had weather-related problems.

[7] According to Peca Popović, the funds raised from the sales of the "Za milion godina" single were US$256,000 and further US$170,000 from the concert tickets, for a grand total of US$426,000.

[19]In 2011, Mladen Popović made a similar statement for the documentary series Rockovnik: It was significant that, at the time, we were the ones helping the people in need, and, unfortunately, only several years later, it was us receiving [humanitarian] aid from the world.

[21] In 2020, in the midst of COVID-19 pandemic, a group of public figures from Serbia recorded a new version of the song, accompanied by the message "Be a Hero, Stay at Home".

The participants included musicians Aleksandra Radović, Sergej Ćetković, Aleksandra Kovač, Zoran Živanović and Jelena Galonić, Bojana Stamenov, Dženan Lončarević, Nevena Božović, Ivana Peters, Goran Šepa, Nenad Milosavljević, Tijana Bogićević, Lena Kovačević, Zoran "Kiki" Lesendrić, Bilja Krstić, Ana Stanić, Leontina Vukomanović and Tijana Dapčević, actors Gordan Kičić, Nebojša Milovanović, Marko Živić (who would himself die from COVID-19 in October 2021[22]) and Gorica Popović, and other musicians and actors.
