You make a good point about the disclaimer Martin. At the very least, they should mention the names of the performers in the group in all ads.

I am probably in the minority on this, but I would hope that if Bob can't come out of "retirement" to re-join the Kingston Trio, the Trio continue on. As Jerry Rasmussen pointed out, some of the vocal groups can carry on and uphold the original sound with respect. Guy Lombardo's Royal Canadians still tour, as does the Glenn Miller Orchestra. I would hope that audiences for those big bands are going to the concerts to see the namesakes, but they are trying to recapture a feeling or perhaps to experience it for the first time. The same can be true with the Kingston Trio. I would hope that they don't try to pull the wool over anyones eyes. I doubt they would do that.

A group can be more than an individual name. Although, I am reminded of the story about the guy that owned the ax that George Washington used to chop down the cherry tree.   The blade fell off about 50 years ago and they had to replace it with a new one. About 10 years ago the handle broke off and they put on a new one. Still, it is the ax the George used!!!!
