Harpers So Solid CrewWycombe Royal Moving kick off forward 15 minutes will not increase the attendance, it is more likely to reduce it. I for one would struggle to get to the match in time for a 7.45pm kick off and so would many others, especially those that have a long commute (a lot of people in Reading and the surrounding areas work in London).
Used to be 7-30 at EP through the 70's. people managed, and night games where better there than the weekend games, IMHO. I would say many memorable games were in the evenings.
Things have changed since then,most notably the number of people trying to get to matches.
