My sister's husband passed away last week, and the funeral was last Saturday. After the typical commercial for the WTS, the speaker invited those in the audience to join in singing song #15(Life Without End at Last). They passed out lyrics to the song to those without songbooks. They have done this at the last three JW funerals I have gone to. I don't remember ever singing at them before that. Maybe I'm just remembering wrong.
I found the whole thing to be rather awkward and presumptuous, given the fact that there were many in attendance who weren't JWs. I also found it extremely hypocritical, considering most JWs would never set foot in another church, much less join in singing one of their hymns.
