Bathed in blistering white light, frontman Matty Healy came out swinging, clutching a pint of Guinness with a cigarette permanently affixed above his ear – a near-caricature of the gloomy, near-grungy rock star he started out as with the band's 2013 self-titled LP.

Glastonbury viewers have been left frustrated after the BBC’s iPlayer service appeared to “crash” during Friday’s headline set by The 1975. The pop-rock group played their only gig of the year at the festival, attracting a huge crowd to the Pyramid Stage for their eagerly anticipated performance.

The 1975 are set to play the Pyramid Stage at Glastonbury on Friday, June 27, with the set expected to start no earlier than 10:15 p.m. BST in the UK. That makes it a 5:15 p.m. ET or 2:15 p.m. PT start in the US and Canada, while for music fans in Australia the show is set to get underway at 7:15 a.m. AEST on Saturday morning.
