In a series of Live Earth concerts across seven continents, rock bands sent out an SOS to the planet on Saturday – and kicked off 24 hours of partying on a global scale.
"There's a lot of talk about saving energy," London headliner Madonna told the Wembley Stadium crowd in introducing her hit "Ray of Light." "But right now I don't want anyone to conserve your energy. I want to see this whole stadium jumping!"
Actress Thandie Newton earlier told the London audience that the global party "increases your attractiveness by 200 percent to a potential mate." Just look at George Clooney, she said.
"I was hanging with (him) recently and I was thinking to myself: He was nothing until he had that teeny tiny electric car," she said.
The London show opened with a drumming session by a troupe calling themselves the SOS All Stars led by Taylor Hawkins of the Foo Fighters, Roger Taylor of Queen and Chad Smith of Red Hot Chili Peppers.
Guest presenter comedian Eddie Izzard recognized the criticism that has been thrown at some of the biggest entertainers in the world – the same people who use private jets to move from appearance to appearance.
"We are probably more guilty than anyone with all this flying around and stuff," he told the 65,000-strong crowd.
Live Earth is organized by former Vice President Al Gore with the aim of raising awareness about global warming. More than 100 acts signed up to play in a 24-hour marathon of shows on seven continents in front of an estimated audience of 2 billion who will watch on TV and over the Internet.
The Wembley concert followed gigs in Sydney and Tokyo. Later, at Giants Stadium in New Jersey, a massive bash starring Bon Jovi, The Police, Keith Urban, Kanye West and Kelly Clarkson kicked off the American party.
In an address to the first concert in Sydney, Australia, Gore appeared, telling the crowd, "Now is the time to begin to heal the planet," Reuters reports.
