More likely the cheque books were being waved about last night. NME is suggesting two wembley stadium dates are 'on hold'. There may be substance in that with other artists announcing London stadium gigs elsewhere (Springsteen, Iron Maiden, Bon Jovi and the Foo Fighters new date taking place in Manchester rather than a third wembley show) and Wembley ( I believe) only being allowed a certain number of concerts. Perhap's playing select stadiums will relieve the fear of arena fatigue.
