Someone’s built a Screenhenge on the Pyramid Stage – a semi-circle of twelve-foot monoliths blaring out visuals of tunnels and galaxies, designed to worship the return of Two Door Cinema Club. They’re a band possessed of the sort of welly-flailing jitter-pop tunes capable of making a soaked and miserable Glastonbury as happy as 93-year-old mums everywhere, and they bowl into their comeback hour with sass and panache. “It’s mind-blowing how many people are here,” says Alex Trimble, floppy of hair and Mid-Atlantic of accent these days, and it’s just as staggering how Two Door manage to tickle the dance-like-a-ferret-on-poppers nodes of the entire field and make you almost believe you’re at a tropical limbo party rather than a place that looks like God’s own long-drop.

Their caper, traditionally, has been two-fold. First, tunnel into Foals’ vault of itchy, high-end afrobeat math-pop tunes and grab the most flawless examples they can find. Next, re-spray them with shiny pop melodies and harmonic sunshine and flog them wholesale to the masses. It’s worked spectacularly – witness the field-wide frugging to ‘Undercover Martyn’, the celestial ad-rock of ‘This Is The Life’ and tropical tongue-twister ‘Something Good Can Work’. In a muddy field, to hear them play ‘Do You Want It All’ with its ping-ponging riffs and vocal hopscotch, ‘I Can Talk’ with its robot cheerleaders and jitterfunk mania, or ‘Changing Of The Seasons’, Alex’s begging booty call to a disinterested ex, is to know what it’s like for your legs to vote Leave from the rest of your body and dance off towards disaster.

A glut of vital, immaculate tunes like ‘Someday’, ‘What You Know’ and the flawless ‘Next Year’ prove they’re masters of their self-formulated art, but after four years of mildly acrimonious hiatus they’re determined to shake up their sound, as much for their own sanity as their fans’ pleasure. Hence the UK premieres of ‘Gameshow’, their third album’s title track and a motorik pop masterpiece about the façade of fame and success, and new single ‘Are We Ready? (Wreck)’, which involves a (sadly pre-recorded) choir of funk kids; experimental pop pieces reflecting the three years they spent apart, poring over their successes and mistakes and working through their individual self-discoveries. Today they return to the UK looking like a band reborn: vibrant, confident, united, bright-futured. Shame the same can’t be said about the UK.
