When I was about six or seven, my brother, a year older than me, chose United. That sealed it for me. Hobson's choice - City. We didn't have a TV, and one of my earliest memories was aged eight, reading a headline "A Tale of Two Cities", the day after the 1969 FA Cup final.
City trained in Wythenshawe Park at the time, so we used to go watch them. It was brilliant. Colin Bell was supremely fit. Lee and Corrigan used to come last in the long run.
My first game was against West Ham, in the early seventies. I think we won 3-1, but can't swear to it. Clive Best played. Our neighbour took me with his lads. He uses to write Coronation Street. One of his lads is now a judge, and still a City fan.
