Following the artistic performances, a parade of nations (staged by 5 time Olympic Choreographer Doug Jack) entered the stadium with over 10,500 athletes walking under the banners of 201 nations. The nations were arranged according to Greek alphabet making Finland, Fiji, Chile, and Hong Kong the last four to enter the stadium before the Greek delegation. On this occasion, in observance of the tradition that the delegation of Greece opens the parade and the host nation closes it, the Greek flag bearer opened the parade and all the Greek delegation closed it. Based on audience reaction, the emotional high point of the parade was the entrance of the delegation from Afghanistan which had been absent from the Olympics and had female competitors for the first time. The Iraqi delegation also stirred emotions. Also recognized was the symbolic unified march of athletes from North Korea and South Korea under the Korean Unification Flag. The country of Kiribati made a debut at these games and East Timor made a debut under its own flag. After the Parade of Nations, during which the Dutch DJ Tiësto provided the music, the Icelandic singer Björk performed the song Oceania, written specially for the event by her and the poet Sjón.
