I think the key thing to remember is that in all the info that has leaked out, I don't think the speakers at the meeting explicitly stated that the GB is the FDS. The term used was something along the lines of 'group of faithful anointed ones preparing spiritual food'. So even if there was no official GB, there was a 'group of faithful anointed ones preparing spiritual food' from 1919. Through careful use of words, they have covered their backsides. Still, it doesn't explain why the 'group of faithful anointed ones preparing spiritual food' up until 1919 are now considered to not be part of the FDS.
Plus a bunch of other questions too. I guess we will have to wait for a letter or WT article to get the 'official word', and then we can pick apart properly.
With regards to the choir, Cedars started a thread in which he noted that he had added to his recent article some notes that were taken at the meeting. In there it mentioned and showed a photo of a choir of children who sang 'Listen, Obey and be Blessed'.
I cannot communicate clearly enough just how much I despise that song. But thats another subject for another day on another thread....
