Back in the 1970s when I was working at a TV research facility I used to organise midweek trips by coach to Wembley to see England play. The total cost was less than a fiver but I remember the match ticket prices starting off at about £1.50 and steadily increasing to about £3.50 in just a few years. I used to order them direct from Wembley Stadium and they would arrive by Registered Letter.
As an aside, seeing your user name I should let you know that my neighbours are still in occasional touch with Ivan and this Christmas they received a card from him.
