Also, I went to school outside Stockport, most of my mates were United, City and Liverpool fans. I used to take Tea Party on the school bus and it would get passed around. People loved it. They took a huge interest in County because of my love for them. County players became household names in my year at school and Tea Party culture was a big part of that. “hope your next shit’s a hedgehog” became a regular insult!
