Pretenders have announced they will be performing a secret set at this year's Glastonbury Festival, which kicks off tomorrow.
The iconic Worthy Farm festival, which takes place in June every year, spoils fans for choice with acts performing from morning until night across the action-packed weekend.
This year the festival's main stage, the Pyramid Stage, will be headlined by Arctic Monkeys – although their appearance is up in the air – Guns n' Roses and Elton John. But, every year, the festival also delights fans with a string of surprise acts performing secret sets dotted around the sprawling eight-and-a-half-mile grounds.
