They have only had eight weeks to prepare for the Live 8 concerts which, because of their global nature and size, are comparable to the Olympics in scale but everything has gone up as if by magic and the crowds are gathering in Europe.Hyde Park in London is expecting a huge crowd drawn by its mouthwatering bill, including Pink Floyd, reforming for the first time in 25 years. In Berlin the final soundchecks have been completed, and the music begins around 2pm CET. The music comes courtesy, among others, from Brian Wilson, Crosby, Stills, and Nash, and a reformed Roxy Music. If it is guaranteed sunshine you are after, Rome is basking in it already, and when the music plays the crowd will be serenaded by mostly Italian artists, although Duran Duran and Noa from Israel are also playing. With all the controversy about the lack of African artists being invited to the events, at least Paris has Youssou N’Dour. Sheryl Crow is taking a break from following Lance Armstrong around the Tour de France, and The Cure, Shakira, and Dido also play.
