Coldplay singer Chris Martin stunned pub-goers in North East Somerset on Sunday evening (June 26) as he gave a performance on piano.

The 45-year-old had just visited Glastonbury Music Festival, attended by 200,000 that weekend, but played to a much smaller gathering at The Stag Inn in Hinton Charterhouse.

The singer-songwriter hopped onto the piano after a couple at the pub, currently planning their wedding, mentioned their first song will be Coldplay’s A Sky Full of Stars.

In a video posted to the pub’s Twitter account, the star asks the couple their names before playing his band’s hit song to the room.

Pub owner Steve Parkin described it as “the most surreal five minutes ever”.

Speaking to the PA News Agency he said: "He just said, ‘Well, do you want me to play it?’ It was really brilliant, a brilliant moment.

“It’s always a little bit of a shock, things like that.

“It was one of those things where you go, ‘Right, this is happening.”

Mr Parkin described the moment earlier on when Martin walked into his pub alongside Dakota Johnson – the daughter of Hollywood stars Melanie Griffith and Don Johnson – whom he did not recognise.

“I said, ‘He looks a bit like Chris Martin’,” he said.

“And his PA said ‘Yes, that is Chris Martin’.”

“I had absolutely no idea (who Dakota Johnson was). The younger girls in the kitchen were like, ‘That’s Dakota Johnson! She’s really famous!'”

Mr Parkin also introduced Martin to his 13-year-old son, Alfred, who is a budding pianist.

“He can play Clocks and can play various songs of theirs and (he is) classically trained on the piano” he said of his son.

“And in fact, (it was) the only reason I stopped him… I said, ‘I hate all that camera in-your-face business. But you wouldn’t just say hello to my son?’

“And he just went, ‘Yeah, no problem.’ He was lovely.”
