Fresh from its success in eliminating global poverty in 2005, the world of rock music is back to tackle the Big One:
More than 200,000 people registered for tickets to the Live Earth concert at Wembley Stadium, organisers have said.
Interested fans had 72 hours from Friday to Monday to register before a ballot to distribute the £55 tickets.
Madonna, James Blunt and the Red Hot Chili Peppers are among the 17 acts confirmed for the concert, which aims to raise awareness of climate change.
The only way 'awareness of climate change' could be raised any higher than its current Himalayan heights would be if the Government paid students to come round to your house, beat drums and repeatedly scream "Anthropogenic Global Warming!" through your letterbox, without pause, for a week.
But this concert's heart is in the right place, I'm sure. Doubtless the Greatest Hits collections of Madonna and the Chili Peppers can always do with a bit of awareness-raising.
