Jeremy Corbyn spoke of his hopes for an end to people living on "the margins of society, euphemistically known as the Fourth World" in a speech focused on issues of social justice and equality delivered on-stage at the Glastonbury festival in England.
Alastair Monty, 29, from London, said: "People are saying exciting things about when he's talking at events".
"When people think the same and co-operate the same, peace is possible and can be achieved".
As is Radiohead's way, there were more than a fair few perplexing, meandering and frankly tiresome moments in the two-hour set, where their challenging experimental electronica and Thom Yorke's pained warbling fell flat, leading the crowd to thin out long before the end. "The elites got it wrong", he said. "That means sharing the wealth out in every part of the country".
Ok, we've all seen novelty flags at Glastonbury over the years, but nothing has captured the zeitgeist of 2017 quite like this effort that pays tribute to that noble tradition, a big bag of cans with the lads.
"Rise like lions after slumber, in unvanquishable number, shake your chains to earth like dew, which in sleep had fallen on you - ye are many, they are few".
He was led on stage by 81-year-old festival founder Michael Eavis.
Hundreds of normally tranquil revellers at the Silent Disco (a dance tent where people listen to music on headphones) started chanting his name to the tune of The White Stripes" "Seven Nation Army'. "Politics is about the lives of all of us".
"I think more politicians should do things like this", said Claire Herbert, 32, from Llanelli, South Wales. "They need to communicate for the people who will be voting for them", she said.
During Friday's headline slot, Radiohead frontman Thom Yorke recited Mrs May's "strong and stable" election slogan, with crowds chanting "Oh, Jeremy Corbyn".
"I wouldn't call myself a fan but he has done good things".
And Michael Vale, 28, from London, said: "I'm not sure they'd get Theresa to do this".
But Darren Garrett, from Gillingham in Dorset, took a different view. "I voted Conservative. I really like Theresa May, I think she has more balls than he will ever have".
Appearing between British singer-songwriter Craig David and US rap act Run The Jewels, Corbyn - who promised during campaigning to abolish tuition fees - said he was proud to have led Labour into an election that delivered the biggest increase in the party's support since 1945.
