Absolutely no idea but my mum says she took me to my first game when I was about 6 or 7 and that would make it mid 60's.I will never forget clambering up the concrete steps (they seemed huge) and looking down to see this beautiful green pitch in the middle of London.
I was hooked from the moment I went to SB. That coupled with being born in Chelsea helped.
First game I remember was a Wolves/ Newcastle game, maybe, god knows. In fact I am consistently impressed with how much some people remember. I can remember some games but they all seem to meld into one overall sense of excitement, passion and commitment.
I do remember going one season and not seeing us win until we played in the FA cup. I was sure it down to me until we carried on losing whether I was there or not.
