THE Bee Gees brothers BARRY and Robin Gibb insist their late brother Maurice joined them on stage, in spirit, at their first UK performance since he died. The group returned to perform at the Prince's Trust charity concert in London last week (20MAY06), as a duo for the first time. But they maintain they felt Maurice was with them throughout their performance. The singer suffered a fatal heart attack during surgery in January 2001, aged 53 - thirteen years after another Gibb brother, ANDY, died. Barry says, "Mo is still with us. When I am on stage, I look to the left and he is there. He is everywhere when we are playing." Robin adds, "It's a spiritual presence. It has taken us two years to be able to perform again without him but getting on stage felt totally right." And Barry insists the gig was the first of many, now the brothers are back: "We're going to keep on playing. We've lost two brothers. Now we are going to make sure we don't lose each other."
