I am looking for help in finding the date of the match between Slade Green and Charlton Athletic, which opened their Floodlights. The programme has no dates in it at all. I original deduced it is 89/90 because of the players line ups. I now also have information from an earlier Slade Green programme that season, that Charlton would be playing a game in October to open the floodlights.

Grateful for any help.
