Maybe it was taped for members who were unable to attend the wake.
I always remember wakes being discouraged (especially open-casket...one sister was frowned upon for having an open-casket funeral for her 3 yo son who died of liver cancer even though it appeared it was mostly to appease her non-believing husband). The preferred method was cremation and a funeral talk at the KH...nobody even going to the gravesite afterward or anything. It kept costs at a minimum; less money spent on caskets and elaborate wake/funeral proceedings meant more money could go into the donation boxes instead. I remember loved ones of the deceased asking people to donate to the hall instead of the family. Giess they thought (or were told) this was the more "christian" way to handle things and would be what their deceased JW family member would have wanted.
