Glastonbury 2015: Pharrell Williams, Patti Smith, Florence and the Machine added to line-up

Glastonbury 2015 just got even more exciting as Pharrell Williams, Patti Smith and Florence And The Machine are among the artists that have been added to the first line-up.

More than 70 acts were announced by festival organisers on 14 April, with Mary J. Blige, The Vaccines, FKA Twigs, The Chemical Brothers, Clean Bandit and Paloma Faith, also heading to Somerset's Worthy Farm in June.

Fans are no doubt anticipating Florence's set as it will be the band's first performance at the festival since 2010. They are expected to play tracks from their new album Horses.

Adding to the eclectic mix of artists are dance acts, Deadmau5, Jamie XX, Hot Chip and chart-toppers Rudimental, whose set at the festival in 2014 was cut short due to a storm over the iconic Pyramid Stage.

Jazz singer George Porter will also be making an appearance while legendary Motown crooner Lionel Richie was previously announced and will be introduced to the stage by the Dalai Lama, real name Tenzin Gyatso.

The reaction from ticket-holders and hopeful festival-goers has been mostly positive so far, most likely due to the wide-ranging line-up:

It contrasts the outrage in March when rapper Kanye West was announced as the headliner for Saturday, with many complaining at the inclusion of a hip hop artist.

One disgruntled man even launched a petition on Change.org to ban West, 37, from performing at Europe's biggest music event.

The petition claimed that the All Day hitmaker is "an insult to music fans all over the world" and described his headline slot as a "musical injustice". The campaign has so far attracted more than 133,000 supporters.

Joining West on the headline bill are the Foo Fighters who will be gracing the Pyramid Stage on the Friday.

This year's Glastonbury festival will take place from 24 June - 28 June.
