Many late additions have also been added to the bill including Klaxons, N.E.R.D. and The Magic Numbers.

To give fans a taster of what's to come a host of bands will perform at the festival on Thursday night including Metronomy, Golden Silvers, Hot Chip, and East 17.

Maximo Park will kick off the festival on the Queens Head stage

Mystery Jets will also be DJing ahead of the opening day.

The weather at the festival is notoriously unpredictable and this year forecasters are warning take your wellies. They're predicting torrential thunderstorms on Friday.

In 2005, storms and flash flooding caused havoc at the site, with many having to use their tents as makeshift boats to float around waterlogged areas.

In 2007, more rain ensured a similar mud bath and many fans struggled to get off site when the festival ended due to the rainy conditions.

Over 200 acts are due to perform over 20 stages across the sell-out weekend. All 137,000 tickets are long gone.
