SHANGHAI'S display of entrepreneurship at the Games will reach its climax when Spanish crooner Julio Iglesias sings love songs at the closing ceremony for free, the organisers said yesterday. ''It was very difficult. We negotiated many times with his manager,'' said Mr Wang Shaoyunan, who is in charge of the opening and closing ceremonies. The organisers had even tried to have US superstar Michael Jackson grace the opening ceremony on Sunday, also free of charge. ''We failed. We were told he was injured in an accident,'' Mr Wang said. Iglesias will sing alone and then be joined by Chinese songstress Wei Wei in a duet at the 18,000-seat Shanghai Gymnasium.
