Coldplay channel Charlie Chaplin in record fourth Glastonbury headline slot
Coldplay began their set on Glastonbury Festival's Pyramid Stage by broadcasting Charlie Chaplin's speech from The Great Dictator.
The words to the 1940 speech include: "I should like to help everyone - if possible - Jew, Gentile - black man - white. We all want to help one another.
"Human beings are like that. We want to live by each other's happiness - not by each other's misery."
The band then came bouncing on to the stage, seguing straight into singing A Head Full Of Dreams and launching fireworks and confetti.
Martin said: "Oh, it's our favourite place in the world."
After performing in 2002, 2005 and 2011, Coldplay are now the only band ever to headline the festival four times.
Coldplay then took the audience back to 2000, playing one of their best-known songs, Yellow.
Chris Martin said the audience had restored his "faith in the world".
He said: " Well good evening everybody, thank you so much for waiting through three days of rain and mud and sticking around. That means the world to us.
"We came here a little bit scared about the state of the world, but the vibe at Glastonbury makes me feel like people are great and together we can do wonderful, wonderful things.
"Thank you for restoring my faith in the world and we're going to give it everything we can tonight for you."
The band then launched into Every Teardrop Is A Waterfall.
As Martin sang the lyric "still I raise the flag", he unfurled a flag reading "love".
Martin sat down at a piano decorated with flowers to perform The Scientist, before the band played new song Birds and fan favourite Paradise.
He paused again to praise the audience for still being cheerful despite experiencing "the collapse of a country" in the aftermath of the European Union referendum.
He said: " Can you turn the lights on please so we can say hello? That's a brave and wonderful bunch of people.
"I was walking around all yesterday with my two kids, Apple and Moses, and I take my proverbial hat off to everyone who's been here through the rain and mud and the carnage essentially, the collapse of a country, everything.
"You've been through everything in the last few days and you're still looking wonderful and happy and together and positive and all the great things that link us."
He then launched into Everglow from new album A Head Full Of Dreams, but quickly discovered there was a technical hitch.
He said: " What's going on, man? One of us is really out of tune."
After stopping the song to discuss the issue with the rest of his band, he said: " That's a terrible problem live at Glastonbury, shall we skip to the next song?"
He then decided to continue the song alone, explaining: "I can do it. Having introduced the rest of the best band in my lifetime, they've left me on my own.
"There's something wrong with the piano but we can muster through."
The audience was bathed in light as the LED-filled "xylobands" given to everyone at the concert flashed and lit up in a synchronised display, while t he headliners played classics including Clocks and Charlie Brown.
Despite rumours Beyonce could be brought on as a special guest, there was no sign of the pop star as Coldplay performed Hymn For The Weekend.
Martin strolled out on a platform into the audience as he performed the band's anthem Fix You.
Martin announced that instead of paying tribute to the late David Bowie by singing Heroes, Coldplay would instead use their Glastonbury appearance to recognise the young band Viola Beach.
The four-piece - Kris Leonard, River Reeves, Tomas Lowe and Jack Dakin - died with their manager Craig Tarry in February when their car plunged more than 80ft into a canal in Sodertalje, Sweden.
Martin said: " We're on tour right now, and normally what we do at this point in our concert is play Heroes by David Bowie, and it's great - the song, not the version.
"But what we're going to do tonight is something a little different ... this year in the beginning of the year, maybe you read about a beautiful young band called Viola Beach, a band that just got signed and were on their first tour of the world and were in a tragic accident and they got taken away and we as a band thought that was just the worst.
"It just reminded us of us and all the other bands that come through here, the excitement and the joy and the hope and we really felt that in them.
"And so we decided as a band, instead of playing Heroes tonight, we're going to create Viola Beach's alternate future for them and let them headline Glastonbury with their song.
"So Kris and Jack and River and Tomas and their manager Craig, this is what would have maybe been you in 20 years or so and I hope we do this song justice."
He called on fans to send the song "up the charts tomorrow", before Coldplay launched into Boys That Sing by Viola Beach as images of the band played behind them.
Coldplay made festival organiser Michael Eavis's dream come true when he fulfilled his special request for a Bee Gees song - and brought Barry Gibb himself on stage.
Martin said: " As we're coming towards the finale of Glastonbury 2016, were going to pull out some special tricks. From someone special, we're going to take a request from Instagram."
Eavis's face appeared on the big screen. He explained: " Michael here. People keep asking me time and time again, which bands of the world should I have playing the festival.
"Most have died actually but there's one that I seriously wanted, of course it was the Bee Gees, fantastic band, lovely songs, loved the world all over, and maybe you chaps would like to play one or two of them."
Martin said: " That's Sir Michael Eavis, the king of music, we can do one better and bring on an actual Bee Gee. Here's Mr Barry Gibb. Let's be respectful."
With Martin and the rest of the band, Gibb then performed the Bee Gees hit To Love Somebody.
The Coldplay frontman told the crowd: "Now we're going to have a Glastonbury referendum, it's very important.
"Those who want Barry Gibb to leave the stage, speak now. Listen to that, nobody. Those of you who want Barry Gibb to remain and play the greatest song of all time..."
After the crowd roared, Coldplay and their special guest performed 1977 hit Stayin' Alive.
Martin paid tribute to artists including Prince and Bowie.
He said: " Let's make some more noise for the Bee Gees and Prince and Bowie and all the bands that don't exist any more and to Barry for bringing the Bee Gees back and making us feel so good.
"Thank you to everyone who's written these incredible songs we get to sing."
The band then played an encore, treating fans to A Sky Full Of Stars and and new single Up&Up.
Children including Apple and Moses joined the band on stage to add their voices to the song, with their mother Gwyneth Paltrow snapping photos of the performance from the side of the stage.
As Martin finished the song, he said: " We've come to the end, shit.
"We want to say thank you ... to the Eavises, the cows, but most of all, Michael and Emily and all of us who get to play would like to thank you for going through everything you've gone through to make this festival the most special place on earth as far as we're concerned.
"In fact you know what, I don't want this to be the last song."
Is there anyone we can speak to to make this not the last song? Is there anyone we can speak to who's in charge? Come we speak to someone in charge? Someone with some power?"
Mr Eavis then walked on to stage.
Martin said: "The perfect person. Michael, can we do one more song please?"
He added: "We'll do one more and this is going to be special. Let's bring on the best singer of all time."
The audience were then treated to a performance of Frank Sinatra's My Way by the 80-year-old festival founder.
