I tried your link, Corby, and got - not sure what alphabet, not Arabic or Hebrew. Unless you are in a High or Higher Area, it seems that current rules pertain. I went to the funeral of an older lady last week and stood outside with about 20 other people for about an hour (very hard on the back) and tried to listen in - those nearest relayed what they could get and someone nipped in and collected hymn books. The outside party sang heartily, the inside ones couldn't. I spoke to a churchwarden the other day and, apparently, outside singing is also verboten. Well, oops!, too late now, but why is Church law so much stricter than national law?
I am interested in the answer because, eventually, I was driven to resign from the P.C.C., not least because of closing the church when the law of the land allowed it to stay open. :(
PS They are trying to get me back into the fold.
