Nick Barnfield of Associated Theatre Services
"A lot of work goes into putting on a concert of this magnitide, especially behind the scenes. Nick Barnfield worked at Associated Theatre Services which provided the rigging, the roof and the stage for the concert. They weren't hard to miss... delivering a huge trailor that contained the stage, lighting and sound equipment. The stage itself was one of the largest mobile plateforms in the world at that time. It had six hinged sections which unfolded with the use of wire and a hydraulic wrench."
