My first game was in October 1948. Can't remember who we played.
In those days we had a brass band playing before kick-off and at half time.
There was no tannoy system. Team changes were chalked on to a blackboard and carried round in front of the spectators by a ball boy.
Players didn't warm up as they do now. They would emerge just a few minutes before kick off and have a brief kick-about.
There were no substitutes.
Players did not do elaborate goal celebrations. A brief handshake from team mates was the norm. No hugging!
Players didn't have any advertising, or their names, on their shirts.
There was no "away kit". If there was a clash of colours they usually wore white shirts.
There were no yellow or red cards. However a player could have his name taken by the ref, or in extreme circumstances, sent off.
Managers did not sit in a dug out. They usually watched from the stand.
Spectators were not segregated. They were generally well-behaved. If younger ones misbehaved they would probably be put in their place by adults.
Because of the three-sided ground, spectators could walk to the opposite end. I used to start off behind the goal at the Bramall Lane end, and move to the kop for the second half.
There were no floodlights so in the depths of winter kick-off could be around 2 pm, or even earlier.
The half time break was around 10 minutes only.
Charity collections were quite common. People would walk round the edge of the pitch with a big blanket and spectators would be urged to throw coins into it. For kids standing near the fence it was not unusual to be hit by a coin on the back of the head. Health and safety...?
The grass would soon wear away. By November, most of the Bramall Lane pitch was bare, sometimes with a top dressing of sand.
There was no undersoil heating.
The toilets were foul!
There was no TV and no local radio. We relied on local papers, expecially the Green 'Un. If they were playing away, we'd listen to 'Sports Report' at 5 pm on the Light Programme to hear the scores. However, the reserve team usually played at the same time as the first team, and the scores would be posted in front of the Cricket Pavilion, so reserve matches were quite well-attended.
... there's so much more I could say, but that's probably enough for now.
