of a samba, chorinho and the bossa nova's rhythm played by the battery of samba schools which made a huge corridor when the athletes from the 42 nations passed between them. There was expectation about the entry of Panama's delegation due to interference by the Panamanian government on their national Olympic committee, the IOC have banned the participation of the country in official events but the PASO required the Panamanian athletes to participate using their organization's flag, so the IOC came back to the decision and authorised the participation of Panama. At this games were created the PASO's anthem, composed by André Mehmari and performed by Orquestra Sinfônica Brasileira conducted by Roberto Minczuk. The show were divided in three parts: "A energia do Sol" (The energy of sun), "A energia da água" (the energy of water), and "A energia do homem" (The man's energy). The show was coordinated by Rosa Magalhães from the Rio de Janeiro samba school GRES Imperatriz Leopoldinense. The oath of the athletes was performed by Brazilian taekwondo athlete Natália Falavigna. Contrary to plan and tradition, the games were not opened by Brazil's head of state, President Luiz Inácio Lula da Silva, but by the head of the Brazilian Olympic Committee, Carlos Arthur Nuzman. Prior to the official opening, Lula had been repeatedly booed whenever the in-stadium camera showed him on the large screen set up inside the stadium.
