Maybe it's us old ones who don't like the thought of playing in white - because of our enemies up the road.
I do remember the time up at Bloomfield Road, Blackpool on New Year's Day 1972, when Watford came out in (horror of horrors) white shirts, black shorts and were soundly booed for the whole game by the Watford fans. We lost 5-0.
George Kirby, manager at the time, commented that we should have been cheering the team, no matter what colour they played in.
He was roundly & soundly criticised in the letter column in the WO for weeks afterwards............
