You might laugh, but when my mother died, we had a Requiem Mass for her, as she would have wished- and intended to do what we've always done at Catholic funerals or weddings, which is follow what everyone else does (we forgot the moves years ago). But- we were family- front row- couldn't see everyone else. The priest eventually took pity on us, and started announbcing, "We stand for this part of the Mass" etc.

I've always thought it was closer to one finger, one thumb keep moving, than to the hokey cokey.
