"I have no quibble with their continuing to call themselves The Weavers. However, when the entire personnel of a small group changes, I just don't see how you can say it's the same group. That was my point with the Peter Paul and Mary example. Extreme, as I said, but I think the point holds."

I don't mean to quibble, but I want to make sure you and anyone reading this understood the point I was trying to make. I don't think the PPM example you gave holds because the group never changed members in their history. We can't imagine it.   However, as you pointed out, the Weavers did and you had no problem with them calling themselves the Weavers. I'm not sure if there is a magic line between 3 or 4 members that allows the name to continue. I think more to the point is that history allowed the Weavers to exist with various personal changes. We can't fathom a PPM without the three original members because it never happened.

Actually, I take that back. Last year Bethanny Yarrow filled in for Mary Travers, but I do think they called themselves Peter, Paul & Bethanny for the gig.

It really is a personal decision for the members of the groups to make, and audience support to allow. It appears that the Kingston Trio will continue to draw from their fan base regardless of the participation of the surviving original members.
