We must be a similar age. I grew up in a non football household, when I was 4 we moved out of Bitterne to a little village in the north of Hampshire as it was close to the M4 that was creeping out of London towards Reading making my Dads regular selling trips to London much easier (M3 was ages away at that time). All the kids at the village primary school were like sheep with that seasons best football teams. Leeds were in their pomp, so joining the herd they became my team too, and one Christmas I get an all white football kit with the Leeds United smiley face badge AND number 4 printed on the back - Billy Bremner. (I even got the funny numbered sock flag). Like I said having no parental guidance on football and school chums following the next best team of the time Derby, QPR, all had a turn (never Liverpool weirdly) most confusing. Thankfully a trip to Granny and Grandads in Shirley and the back pages of the Echo saw a parting of the clouds and a revelatory shaft of light guiding me to where I should go.
Alas I've only done 50 years - so a mere stripling compared to some on here.
