The GB used to be a lot lower profile when I was young , but I do remember a "Special talk" that was organised in a city hall and Ewart Chitty ( who later resigned as a GB member , allegedly for homosexual tendencies and/or alcoholism ) gave a long talk. He was applauded onto the platform and the applause afterwards was the longest and loudest I have ever heard at a JW meeting. After the talk he appeared at the front of the hall and was virtually mobbed. Even as a child back then , I felt somewhat uncomfortable.
One of our elders briefly met Fred Franz at a convention in the USA - he shook his hand and had a brief conversation lasting probably a minute at most. Franz apparently made some sort of comment to the effect that "Armageddon is very near , brother". This incident had a profound affect on the elder - he constantly referenced it in this answers , his talks and items and even in casual conversation - usually alluding to how "the GB know that the end is near" etc. ( The fact that this comment was made in the early 1960's didn't seem to diminish its long term effect. ) I remember once somewhat facetiously mentioning to him that he hadn't spoken about his conversation with Franz for at least two weeks and he suddenly got really angry with me.
