Robbie Williams addresses Glastonbury rumours - as excitement builds for 'secret' sets

Pulp tried to quash the rumours, Robbie Williams was happy to fuel them - sharing a picture of a blue plaque in his name apparently slapped over a famous Glastonbury sign, before seemingly backtracking.

"30 years later..." he captioned his first social media post early on Friday morning - a reference to his headline-grabbing attendance in 1995.

This was the year Williams was famously pictured partying with Oasis's Liam and Noel Gallagher, shunning the boyband shackles with bleached-blonde hair and a blacked-out tooth. The writing was on the wall, and the announcement of his departure from Take That came just a few weeks later.

At Glastonbury this year, is the writing quite literally on the wall for a comeback?

Well, maybe not. A few hours after his post, Williams shared another, less cryptic message to say he would not be performing, along with his list of recommended acts to go and see - The 1975, Busta Rhymes, Charli XCX, Self Esteem and Reverend And The Makers, if you're interested.

Is he bluffing? Double-bluffing? Who knows, but along with celeb spotting and mud, if there's one topic of conversation that makes headlines when it comes to Glastonbury, it's speculation about secret artists. Williams has got everybody talking.

Even before his posts, the Let Me Entertain You singer was among the artists rumoured to be performing secret sets this year, along with Pulp and Haim. Lewis Capaldi and Lorde too, with both "TBA" acts turning out to huge crowds on Friday.

In recent years, these surprise sets have turned into some of the event's most memorable moments - think Foo Fighters as "The ChurnUps" in 2023, Pulp's comeback in 2011, and Lady Gaga treating fans to a small performance in one of the festival's after hours areas, Shangri-La, in 2009.

Franz Ferdinand, famous for hits including Take Me Out and Do You Want To in the mid-2000s, were the first to do it back in 2008. This was actually due to Pete Doherty's band Babyshambles pulling out last-minute, but the approach to announcing the switch was, at the time, a novel one.

While officially, the act was "TBA", frontman Alex Kapranos wasn't great at keeping the secret, worried people might not turn up. He and bandmates handed out fliers, and word spread.

"We played on the Park Stage and we thought, 'nobody's going to know we're playing'," Kapranos told Sky News ahead of a return performance on Friday. "It actually ended up being one of the most amazing gigs we've ever played, people were so up for it and going crazy.

"We weren't keeping it secret. We were walking about like, 'we're playing later on, check it out'. We're a band from Glasgow called Franz Ferdinand."

These now not-so-secret performances have become bigger and bigger as each festival rolls around, with leaks making headlines in the run-up to the event.

Providing handy tips and hints - and often eventually confirmation, just in time for fans to be in position - is the Secret Glasto team. They have no official ties to Glastonbury, but over the years have become a reliable source of information.

The account's founder, who now works in a team of six, spoke to us on site - incognito, of course.

"We've got our own sources and we can start checking things because we've now had enough years that we can check in with several people," he said. "And they trust us because we are quite sensible with when we time announcements, which I think is the key thing."

Sometimes acts themselves will confirm, they said. Their success rate for predictions is "in the low 90%" - but dragged down mainly by inexperience in their first year, which was 2014.

Capaldi's comeback yesterday, two years after struggling on stage at Glastonbury in 2023, was a special moment.

"It was really, really heartwarming to see him get back up," Secret Glasto said. "There was such goodwill in the crowd and it was just magical. It's just what secret sets should be about."

On Saturday evening, a non-existent act called Patchwork have a pretty important billing just before Raye and then headliner Neil Young on the Pyramid Stage.

Pulp keyboard player Candida Doyle dampened rumours by reportedly saying in an interview earlier this month Glastonbury "weren't interested" in booking the band.

But is this true?

"It happens a few times," Secret Glasto said, of artists maybe telling little white lies to keep the secret for as long as possible. "They've got to keep the suspense somehow...

"Sources that we got for Pulp were really, really strong. It's just so exciting for us, for the whole team. This is the most exciting secret set that Glastonbury's ever done."

It's a fine balance - not spoiling the surprise but giving fans enough time to get where they want to be. When a festival is this big - home to around 200,000 people over the weekend - at a lot of stages, fans need to be in place early.

"The point is to always make sure people can get to the set if they wanted to." But if a huge artist is going to surprise fans on a very small stage, sometimes they have to keep schtum for safety concerns over huge crowds. "Sometimes we're like, we can't print this."

So, will Williams be playing? The rumour is that he could be joining his mate Rod Stewart, who is performing on the Pyramid Stage in the "legends" slot on Sunday.

"Robbie Williams entered this area without accreditation, authorisation, or alignment with prevailing taste," according to the blue plaque in his social media tease, of his attendance in 1995. "His presence was uninvited, unofficial and ultimately inevitable."

In his candid documentary series, and biopic Better Man, both released last year, Williams has been open about his struggles with fame and imposter syndrome, and how as an artist known for pop he craved respect from those seen as more credible at a time when indie music reigned.

Officially this year, there is no Robbie Williams on the line-up. Unofficially, who knows? But 30 years since his partying with the Gallaghers, pop music is embraced - and there would be a lot of love for the star if he did make an appearance now.
