Chris Martin brought a fan up on stage last night in Croke Park.
He spotted a fan called Rob crowd-surfing in his wheelchair. He then invited Rob up on stage and the crowd went crazy.
He then introduced Rob, who is a personal trainer, to the crowd of almost 75,000.
Rob came prepared for his stage visit and was handed a harmonica and went on to help Chris Martin out on the next song.
