Liam Gallagher and his band Beady Eye kicked off the world renowned event in Somerset, South West England, this morning 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.

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.

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.'
