Hi Petra ! yes, we were an unusual Congregation for the time, nearby Congregations more than likely made more of the 1975 rubbish than ours did.
We were made up of very old folks who numbered only a few, and young ones who had grown up there, or moved in. The Elders were all "young" at the time, bar one. All of these young guys were NOT " Little Grey Society Men" as they used to call those who used to blindly tow the line.
Shortly before I moved in, an Elder was moved there to be Congregation Servant, just pre-Elders, as the C.O was concerned things were not being done properly. He was a a reasonable guy, and told me when he got there, nobody wore a Tie on the Platform etc, none of the normal Rules stuff. That attitude continued for years, though ties were agreed to be worn. One C.O told me that he had been told by the outgoing C.O to fear going to us, we were all rebels ! The young Elders were pretty well equipped with bullshit detectors, for J.W's.
I never owned a suit for many a year, and gave Public Talks in a jacket and kind of matching trousers (pants). And gave those talks wearing a beard, for many years.I think the easy going attitude of our probably unique Congregation, and its very good Social Life, delayed my waking up and departing much longer than if I had been elsewhere, sadly.
