When I said I was thinking of going I was just talking about the local congregation because I believe there is going to be a live video stream. So no Rock Star autograph. Let me see how I feel on Saturday.
As for the big Bethel being built in the UK, I cannot make a valid comment. In the congregation I was in, anything outside the congregations territory was generally not discussed. Theocratic things were also generally not discussed, after all its not really allowed.
One example, I was talking with a group of brothers at a get together and I explicitly said they should all read Mt. 24, and consider every verse in context, and nothing more. One brother talked to me later and said I should not be encouraging the brothers to read the bible on their own.
