Cross everything you've got. Today's the day you'll find out if you've got tickets to see Madonna, Snow Patrol and James Blunt (to name but a few) at Live Earth – you know, that jolly super concert that's going to stop global warming, or something... You had to apply for tickets by Monday and the successful applicants will find out today – by text! How modern! However, any naughty types hoping to whack their tickets on eBay are in for a shock – they'll be required to donate at least 20 per cent of the final sale price to charity.
