Beyonce eyes Glastonbury slot after Jay-Z success

R&B superstar Beyone Knowles is desperate to headline legendary UK music festival Glastonbury - after her husband Jay-Z's triumphant performance at this year's event.

The '99 Problems' rapper took to the festival's main stage in June amid a flurry of criticism of Glastonbury organisers for booking a hip-hop artist to perform at a rock-orientated event.
