Liam Gallagher admits he was wrong to criticise the Glastonbury festival.

The singer and his band Beady Eye kicked off the world renowned event in Somerset, South West England, this morning (28.06.13) with a surprise gig on The Other Stage.

The group's appearance came as a shock to many after the rocker blasted the festival just a few weeks ago for being full of ''celebrities walking around in their boots'' but after thrilling thousands this morning Liam has conceded his criticism was unfair.

Speaking backstage at the festival, Liam - who played Glastonbury three times with his old band Oasis, first in 1994 then as headliners in 1995 and 2004 - exclusively told BANG Showbiz: ''I had a sh***y gig last time I was here with Oasis, my head was a bit pickled, but we have minds and minds are meant to be changed. I've changed my mind, we've had a good experience today and times before. I take it back.''

Thousands of festival goers went to see Beady Eye open at 11:00am and Liam was thrilled with the atmosphere as they played their set - which included tracks off their new album 'BE' such as 'Flick of the Finger' and 'I'm Just Saying' and Oasis songs 'Morning Glory' and 'Rock 'n' Roll' star.

He said: ''It's all about the music man, that's the thing about this festival, we just sent the music out into the universe and it was all good. We thought there would be no one there ... it was really good.''

Liam's bandmate Gem Archer hopes the band's songs got some of the lazier festival goers out of their tents.

Gem said: ''I'd like to think there were a load of people lying in their tents hearing our lovely music wafting over and coming out to see us with their bleary heads.''

Other acts due to perform today include Rita Ora, Foals, The Horrors and headlining band the Arctic Monkeys.

Glastonbury has partnered with EE for 2013 and the telecoms company have set the first 4G network at a UK festival on site to keep visitors tweeting, blogging and updating their Facebook pages, as well as providing two free recharge tents.
