Tiki reminded me of a few more things. Yes, the public talk was an hour long - *if* the speaker did not go over. Sometimes the (what is the brother that introduces the speaker and the songs, etc called...?? Like an emcee, but that's not what he's called) speaker would be interrupted and told to wrap up in 2 minutes. LOL.
In our hall, the WT study sometimes went WAAAYYYY over the alotted hour. Once by almost 30 minutes. Brutal.
Handbills! I remember those. Speaker's names were omitted very early 70's for us, I think. Then for a couple of years there were just the talk titles.
Purpose of the intermission, as I think I recall better now, was to let the public leave after the advertised talk - but not before being greeted by individuals in the cong and being offered a free home bible study and invited to return the following Sunday. WT study was not that interesting to the public as it contained 'deeper' spiritual (read: crazy) information for discussion.
One of the happiest reports EVER was when the letter was read to limit the Sunday meeting to 2 hours TOTAL.
Start-to-finish, including songs and prayers. Seriously, some of those meetings from the early/mid 70's exceeded 2.5 hours. Add 30 minutes for us (elder's family) to arrive early to open the hall, an elder's meeting after the meeting and/or wait for everyone to vacate so we could lock up... Some days were there 4-6 hours. We brought books to read and homework to do.
