Elton John brings out The Killers frontman Brandon Flowers as special guest at Glastonbury

Fans at Glastonbury have absolutely lost it as Elton John welcomed American rock star Brandon Flowers to the stage to join him for a rendition of

John called The Killers frontman a 'dear friend' before the pair belted out a duet of 'Tiny Dancer'.

Heaving crows turned out for Elton's last-ever show on British soil, with the icon taking the headline spot at the massive annual music festival.

On Sunday (25 June), the 'Crocodile Rock' took to the Pyramid stage to wow his audience with performances of hit back catalogue songs, including 1973’s 'Benny and the Jets'.

The 76-year-old revealed to fans - who were rocking it out at Glastonbury with millions more tuning in on streams around the world - that he met his old pal one fateful night in Las Vegas.

"My next guest I first met in 2005 when I was playing in Las Vegas," he told what may be the largest-ever Glastonbury headlining crowd.

"We’ve been friends ever since. He was the first person I thought of to ask to play with me, even though he’s played Glastonbury six times with The Killers."

Music fans then proceeded to go absolutely wild as the American singer - best known for his song and drunken pub belter When We Were Young.

The British pop legend had teased he would be ringing in four close friends to help him blow the proverbial roof off the UK's largest music festival.

Elton's husband David Furnish confirmed that that the 76-year-old would invite four very special guests on stage, but stopped shot of telling Sky News who they were.

"Four collaborators of his choosing. People he just thought, ‘I’d really like to do something with these artists at Glastonbury'," he said.

He added: "And that’s all I’m going to say."

"It’s a different set list – it’s a huge outdoor live festival. He’s got four different collaborators joining him on stage at different times, who I won’t name, sorry."

Boooooo to that.

Well, we can confirm who those four entertainers are, with the Saturday singer belting out his brilliant back catalogue at time of writing.

So, without further ado, Elton's special guests included the following stars and singers.

Jacob Lusk from the band Gabriels with the London Community Gospel Choir, singing Are You Ready for Love.

Next up was Stephen Sanchez who, for some unknown reason, sang his own song Until I Found You.

Then came the sublime Brandon Flowers of The Killers, with a little ripper of a rendition of Tiny Dancer.

Rina Sawayama brought up the rear to sing Don't Go Breaking My Heart.
