As far as I'm aware of all the UK gigs only Wembley pavilion is all seater....10,000 seats The pavilion is a temporary venue whilst the Arena is being renovated. There are standing areas at all other UK gigs. Cardiff is all standing except for the balcony as is Brixton Academy.
We all of us deeply apologise for this god forsaken shit heap of a building...but we will make it rock.
