U2 as big as we'll ever be: The Edge

U2 are “at the absolute limit” with their 360 Degree tour, and are “as big” as they could “ever get”, according to The Edge.

The ‘Vertigo’ rockers were declared to have the highest grossing tour ever – beating a record set by The Rolling Stones – last week, having made €383.5m with 20 dates to go, but the tour itself is also the most expensive ever staged, taking 120 lorries to transport its 50-metre tall sound system, stage and lighting rig.
