Boy, 12, crowned 'king of the show' by Coldplay

Issac from Northampton was crowned 'king of the show' at the Coldplay concert

A 12-year-old Coldplay fan was hailed as "king of the show" by band frontman Chris Martin after wearing a crown to one of their concerts.

Isaac from Northampton was at Wembley Stadium on Sunday with his family.

He had the crown from when he was performing in a school play, and wore it in the hope of being spotted on the big screen.

"You are in a massive crowd, and I did not think the crown would get me that much attention," he said.

Issac first wore the crown when he watched the Women's Rugby World Cup at Franklin's Gardens in the town, after his school play in June.

"I also got on the big screen there in front of 20,000 people and I did not think I was going to get on to Wembley," he said.

"It was just amazing."

Martin sang a song to Issac, singing: "Hello. Thanks for coming today to see our band play your royal highness the king of this show."

Issac and his family said they were big fans of the band and had previously seen them perform at Radio One Big Weekend last year at Stockwood Park in Luton.

Issac said he did not realise he was on the screen until his dad told him

"I remember [the screen] was showing on me, but I did not see myself and then I remember my dad just tapping me on my back and I saw his face and it went bright red," he added.

Patrick, his father, said it was "a very special show" for them.

"The kids are not allowed to stand so I am glad we were sitting where we were as it worked out for the best," he added.

Issac said his fame on the big screen had resulted in people asking for pictures and signatures when he left the stadium.

He said: "I was walking out of the stadium I felt like a celebrity as everyone was like 'can I get a picture'?"
