The Kingston Trio has lasted 47 years and they didn't do that by making bad decisions. I think if they decide to continue on after Bob Shane's forced retirement, they have the foresight to understand what their audience wants, and that their credibility is in their hands. If they're wrong, then clearly no one will come to see them any more, because they've completely ruined their credibility. If they're right, they will continue. It is their call, IMHO.
