A Coldplay fan in a wheelchair managed to crowd surf to the front so the band invited him on stage

He performed an impromptu song with Chris Martin et al

Chris Martin was so in awe of a fan gliding toward him over the crowd in a wheelchair that he invited the man on stage to help the band sing a song.

29-year-old Rob was passed aloft and along by audience members at the Croke Park, Dublin gig, being spotted by Martin as he neared the stage.

The frontman introduced him to the crowd, with Rob whipping out a harmonica and playing a traditional song with help from Coldplay.

The Dublin gig was part of the band's Head Full of Dreams tour.

"Cead mile failte [a hundred thousand welcomes]," Martin said at the top of the concert.

"We've been away from Ireland and from Dublin for too long.

"I heard a rumour that this crowd was going to be the loudest in history. We're so happy to be here, now turn it up."
