I just had this flashback when commenting on another thread about how they used to announce reproof or DFing from the platform. At least in our congregation, it was a dramatic event (this is what I can remember from back in the mid-late 60's or early 70's when I was a kid).
At the end of the Service Meeting, just before singing the final song, the brother would announce, "We have a letter that must be read."
The "Congregation Servant" (my grandfather or later my father) would then slowly walk from the back of the KH to the platform. We had these wooden floors and they would make a creaking sound as you would walk. But you could hear a pin drop from a mile away. It was actually eerie.
Then he would read that so and so has been reproved or DF'd. He would specifically mention the reason, typically fornication.
Then he would read another paragraph or something and then state the names of the three brothers on the committee (normally the congregation servant, assistant and field service servant or possibly the school servant).
In any case, he would give the details and dates. Then, he would walk off the platform, again slowly, walk to the back of the KH and it seemed like they would not start the song until he has all the way to the back.
It was quite the experience. I don't know if other congregations did it the same way but it was quite a dramatic event.
