The Secretary of State's Inspector, Mr J I McPherson, in giving his decision noted, " The present loss of Wembley Stadium has left the London area short of a venue for the large concerts which used to be staged there. There is considerable demand for such concerts on a worldwide scale and there is a need for some to be held in the UK, preferably the London area, in order to benefit the music industry. At the same time, these concerts would also benefit the tourism industry and the game of rugby union, which is an important component of civilised life."

The Inspector also noted that notwithstanding the RFU's contention that Twickenham Stadium could lawfully be used for concerts, the RFU had chosen to submit a planning application. This gave an opportunity for the matter to be fully discussed. The Inspector imposed a number of conditions which mirrored the restrictions and benefits the RFU had already willingly offered.

The RFU voluntarily gave an undertaking to the local authority which will ensure substantial investment being made in transport, access and safety measures in the stadium area. This will cover the likes of CCTV cameras, cycle routes, pedestrian crossings, signage, parking enforcement and publicity covering all transport and travel related to events at Twickenham. Numbers attending will be a third less than at international matches and significant investment will be made in measures like shuttle buses, which have over the past season increased from ferrying 1,500 supporters out of the area post match to transporting 9,000 fans, an increase of 500% using the free service.
