I remember the run up to 1975 as a young teen.
Looking round the cong I occasionally attend there are about 80 publishers. Of which still now attending at least 12/14 were baptised in or before 1975 and another 4/5 would have been what are now unbaptised publishers aged 10 plus. So 20/25% still would have solid memories of 1975.
Of that group 4 still serve as elders (aged 60's through 80's) and 1 as a min servant. They would have gone through not only 1975 but also the big generation change of 1995 and they're still repeating and parroting and spouting the same old crap as ever.
