I think it's a mixture of Jake's take and the fact that, when I was young, the events seemed much more important to me. As I got older I attended more and more football matches, so the ones from my youth are much more indelibly imprinted on my mind. I could name the scorers and results from most FA Cup finals in the Seventies and Eighties off the top of my head, but recent ones require much greater effort. Ditto the National, Olympics and other major evfents.
