Also in Liverpool (the city)back in the day the biggest team were 100% Everton. Once Liverpool became successful (under Shankly)those percentages began to change. In other words, there were plastic success chasing glory hunters even back in those days.

I know what you’re saying but that is a really modern way of looking at it. This is forgetting a significant thing in the way football fans behaved in the 50s and 60s, at least in Liverpool, can’t speak for other places obviously, but it was extremely common for people to ‘support’ both clubs. You had your preferred chosen side of course but it was far from unusual for people to attend the match of whoever was at home that week, Everton or Liverpool.
