As a JW child of the 1950s, I remember that we had some great "extra-curricular" activities from time to time that really added to my experiences and fond memories.
I was raised in Riverside, CA. There were three (and later four) Kingdom Halls within a 10-mile radius of the downtown area. The city had a great civic auditorium and it was frequently used for circuit assemblies. It was also a great location for special events. For example:
Around 1955, if I remember correctly, one of the brothers from Bethel actually brought out a shortened version of the "PhotoDrama of Creation." It was shown on a large movie theater style screen at the Civic Auditorium. I did not see it again until it appeared on YouTube a couple of years ago. Very impressive. You can see why Russell was so popular at the time and must have gained many converts worldwide as a result of that most magnificent production. The one I saw was tinted (not sure when the tint was added), so you can imagine people in that early period before the first World War being amazed at not only hearing Russell's voice in sync with the movies, but also the fact that they were looking at colored film - possibly for the first time in their lives.
About a year later, a missionary couple came to Riverside and brought movies, slides and recordings with them. Again, the Civic Auditorium was rented and they made their presentation. I remember that their presentation was fun, educational and emotional. I especially remember their recordings of some of the African brothers and sisters singing songs from their version of the Kingdom Songbook - and even a few of their local cultural favorites (something you'd never see now!). Their harmony and skill was amazing. The whole audience stood up and applauded for nearly five minutes after hearing that beautiful music.
I also remember that an occasional brother from Bethel would pass through the area and stop by our Kingdom Hall. Sometimes, after the Thursday night Service Meeting, a visitor would stay over and either speak or answer questions about life at Bethel or Gilead. Families who had to leave could do so, but sometimes the visitor's informal talk would continue until 11 or 11:30 at night. We'd have to leave the area before midnight in order not to violate local noise laws.
I'm sure that some things like this must happen from time to time, but I have not heard of anything quite like what I experienced. Oh, and there is more - but I'll add that later in the thread...
