Re Clough , that was very much a different era, there was an impact on attendances in the very early days of live matches and in Cloughs time clubs were very paranoid in the leaking of the schedule for Match of the Day or the Big Match due to crowd impact.(In the light of the present fuss over iFollow etc) Almost no live football matches on TV.
It's not that long since the only live televised games each season were the FA Cup Final and England v Scotland - both guaranteed to sell out - plus the European Cup Final, at least if an English team was involved, which it often was in the 70's.
Also they used to televise an England Schoolboys game at the end of each season (against West Germany?), since that came under the ESFA and The FA couldn't stop them.
Brian Clough was one of the most vocal against televising live games, on the basis that no-one would ever go out to see a game if they could watch it in the comfort of their own home. So he didn't get everything right.
Maybe he had an extra comfortable home and a very understanding wife? Plus a TV, obviously.
Meanwhle, mention of Eng v Scot brings back memories of the British Championships, more commonly known as the Home Championshps.
