Well, now you ask, I appear to have the date wrong. And we weren't home in time for tea either...
It was 30th June 1977. And we arrived home at 20.15. So I doubt I would have had enough time for supper before bedtime. But we definitely played football, I have a picture of me holding said ball.
I cannot attend, alas, but I am heartened to see you putting the DULL into Wich.
The last time I went to Dulwich was to visit my cousins in the summer of 1978. Well, not all of the them, as one of them was at work. I can find out the exact date if anyone really needs to know. We played football...
