I remember, around 1974, going to a talk by then Vice President Frederick Franz at the Inglewood Public Forum in Southern California. The stadium was jam packed all the way to the floor (seating capacity 17500). He set out his long winded calculations of 1975 then came out with the conclusion that the world would end by 1975 or a few months or years thereafter.
I also remember being in the ministry school meeting one night in 1974 when the Kingdom Ministry was being read. It stated that there were reports of brothers selling their homes in order to spend the short remaining time in the witnessing work and that that was a good thing.
