Actor Johnny Depp made his second Glastonbury Festival appearance as he joined Kris Kristofferson for a live performance on the main Pyramid Stage.

The actor picked up a guitar as he unexpectedly strode onto the stage and played along to the US folk star’s hit Sunday Morning.

The audience – who had been enjoying a low-key acoustic set from the Me & Bobby McGee star – roared as the actor appeared, hours after he made headlines with his controversial comments about US president Donald Trump at one of the festival’s film events on Thursday.

Depp continued to show off his musical skills on Friday afternoon, applauding Kristofferson, who jokingly described him as “my hero”.

It marked an extra special moment for Kristofferson, who turned 81 on Thursday.

Guest stars joined him on stage to play along and wish him a happy birthday.

Appearing at the huge Somerset event during his European tour, he greeted the crowd with a warm “Hello Glastonbury” and joked: “I don’t know where I am” as he worked through a few minor technical hitches.

Earlier today music legend Peter Hook led a minute’s silence on stage to remember those who lost their lives in the Manchester and London attacks, and Grenfell Tower fire.

The co-founder of Joy Division and New Order stood on the Pyramid Stage in front of thousands of people at 10.40am.

Thousands of revellers stood silent, with some waving flags – including those bearing images of the worker bee, a symbol of Manchester, and “We Love MCR”.

Hook’s daughter was at the Ariana Grande gig on May 22 and was taken to hospital, where she spent time on crutches, after being trampled.

“Good morning and welcome to Glastonbury,” the bassist told the sprawling crowds at the festival, where music events officially begin on Friday.

“I have been very kindly asked by the Eavis family to lead this minute’s silence.

“Could we please use it as a chance to send our hopes and our prayers for love and life and freedom – the things that we are here to celebrate.

“We send our sympathies to everyone affected by the events in London and Manchester and everyone affected in Grenfell Tower.

“God bless you all. Thank you.”
