19 of the best Instagram photos of celebrities behind the scenes at Glastonbury

There was no shortage of politics this year, though the atmosphere of the event was distinctly more upbeat than the gloomy sentiment of 2016's post-Brexit Glastonbury. Festival organiser Emily Eavis even said this year's festival was "the best one yet," according to The Guardian.

The gates at Worthy Farm opened at 7 a.m. on Wednesday to chants of "Corbyn, Corbyn, Corbyn," according to The Telegraph, and festival-goers turned up in their droves to listen to Labour leader Jeremy Corbyn's speech on Saturday.

Highlights included performances from Foo Fighters, Katy Perry, Ed Sheeran, Dua Lipa, and Radiohead, among countless others.

However, what was happening within the crowds and behind the scenes was just as interesting.

Every year, the festival is attended by a host of welly-wearing celebrities, and this year was no exception.
