The atmosphere question is merely a product of the change in times and isn't unique to us.
The cup game on Friday was, from the beginning, noticeably louder and enthusiastic than a league game despite there being thousands less in attendance.
Who makes noise? It's not season ticket holders of 60 years. It's not the seated couples of the STFS. It's the "stupid kids in the corner" who pay just as much as every body else to be there.
These stupid kids, however, don't have the luxury of tickets to the football being cheaper than a cinema ticket.
I wonder why the ground is louder when tickets are a tenner?
