Attendances in the '60 and '70s
I was luckier than many kids in that my teacher was a League of Ireland supporter and went to watch Waterford in their heyday , and indeed he still does support them when he can. Through the teacher we at least looked up results of League of Ireand teams. We used to enjoy it when Waterford got beaten by someone. But that didn't begin to happen very often till after we left the school in 1974.
Part of the problem should also be levelled at the clubs concerned. They put none of the fruits of the bigger attendances from the 1950's and 1960's into spectator facilities. And to be honest looking back on it now, many of the grounds in the 1970's were crumbling compared to today. Having said that, some of the results gained by Irish teams in Europe , particularly against English opposition , did a massive disservice to the perception of the game here. Finn Harps got hammered by Everton and Derby County on two seperate occasions in the mid 1970's. Not even the dramatically improved results gained by Dundalk later in the decade and in the early 1980's did much to improve things.
One interesting aside, I have noticed a strange parallel between the early 1980's and now. In the early 1980's Dundalk got some very respectable results in European football at a time when the Republic of Ireland failed to qualify at senior level for major tournaments. Now in the mid naughties (00's)
domestic teams results in European club competitions are again improving in inverse proportion to the fortunes of the the National team.
