That's understandable.I used to go to concerts originally where you were free to leave your seat and go and stand where you want. But I think after the death of a fan at a concert in 1974 the rules about staying in your seat became tighter.
I was at the final concert for the Jam, at Wembley Arena, back in the 80's.
I've not been to a concert, for a good while.
The last concert I was at, was to see the Pogues and the Dropkick Murphy's, at the Metro Arena in Newcastle, around 15 years ago.
