When is a 68-year old socialist politician so cool with the kids that he upstages even the most popular bands?
When his name is JE-REM-Y COR-BYN.

The chorus started at 10pm on Thursday in the dark sweaty depths of the Glastonbury silent disco. Just a low rumbling at first, it built into a loud roar with hundreds of festivalgoers singing, at the tops of their voices: “OH ... JE-REM-Y COR-BYN.”
Glastonbury this year may boast appearances from the biggest acts in the world, Ed Sheeran and Radiohead among them, but judging by the T-shirts, flags and impromptu musical outbursts, the man of the hour is the Labour party’s 68-year-old leader...
Heather Cuss, 33, from south London, said: “There’s always a community atmosphere at Glastonbury but this year it’s definitely all about Jezza. We’ve seen musicians playing with Corbyn necklaces and everywhere you walk you hear people break out into Jeremy Corbyn chants. Even bands from abroad have been giving him a shout out as they’ve clearly heard everyone going, ‘Jeremy Corbyn, Jeremy Corbyn,’ and they’re joining in.”
In the dance area Shangri-La on Thursday, the New York brass band were leading the crowds in the ‘Oh, Jeremy Corbyn’ chant and the giant sand sculpture near the park stage was of Corbyn riding on the back of a fox and chasing Theresa May through fields of wheat.

The JE-REM-Y COR-BYN chant (done to "Seven Nation Army" by the White Stripes) is quite likely the most popular song in Britain today.
Don't believe me?

There is plenty of other videos, but you get the idea.
Corbyn has become so popular that his celebrity status has rubbed off onto his shadow cabinet.

Former shadow chancellor Ed Balls, enjoying his first Glastonbury, was stopped for selfies every five minutes as he walked around Shangri-La and was met with shrieks of delight and songs everywhere he went, to the bemusement of his wife, Yvette Cooper, who hasn’t been to Glastonbury for 30 years.
Andrew Myors, 30, and Matt Foncette, 32, said they had been among those singing the Corbyn when one of the DJs played The White Stripes’ track Seven Nation Army – the backing music for the chant – and the whole field erupted into song.

No amount of money can buy publicity like this.

As you might imagine, all this good publicity is showing up in the polls.

As a new poll finds today, the prospect of Jeremy Corbyn becoming the next prime minister of Great Britain is now very much a real one and it's a prospect Tory MPs are all too aware of.
The YouGov poll for the Times finds that, for the first time ever, the British people now believe Jeremy Corbyn would make a better prime minister than Theresa May.
35% say that the Labour leader would make the "best PM" as opposed to 34% who pick May.
It is a remarkable turnaround for Corbyn, given that at the start of the election campaign May had a 39% lead over Corbyn on who would make the best PM.
It is also the first time since that a leader of the Labour party has taken a lead on this measure since 2007, when Gordon Brown first became prime minister.

Labour has also pulled ahead.

Meanwhile, the Tories have still failed to form a coalition with the D.U.P.

Talks between the Democratic Unionist Party (DUP) and Theresa May reportedly became so tense the Northern Irish party refused to answer the phone to the Prime Minister’s advisers for 36 hours.
The DUP has demanded £2bn investment in health and infrastructure in Northern Ireland, with the party warning it cannot not be “taken for granted”.
