Live Earth U.K. will start with the reunited Genesis and end with Madonna's "Hung Up," according to the London concert's running order released today.
Among the "surprises" set for the show include Justin Timberlake teaming up with Duran Duran on one of the band's new Timbaland-produced songs (and perhaps some songs of his own) and Chris Rock introducing the Red Hot Chili Peppers and Metallica.
