The number of people at Glastonbury this year has been extended from 150,000 people to 175,000 people. In practical terms this means that the site has expanded from the size of a town with the population of Dundee or Swindon to one comparable with Norwich. In any case, the Glastonbury Festival still has more people than notable towns such as Exeter, Cambridge, Oxford, York or Ipswich!
(No, I don't know the population of British towns off by heart - I looked it up before we left!)
On a related note, here's a picture of some aliens asking a local bobby for directions.
