Not mentioned, back in the Kingston Trio's heyday, Dave Guard also took issue with Bob Shane and Nick Reynolds not being able to read music.
Gentlemen: I just wanted to add one more thing regarding the Bob Shane vs Dave Guard fiasco.
I believe the problem may have began with "Scotch & Soda".
Don't forget, it was Dave Guard who brought this song to The Kingston Trio.
At the time he was dating Catherine Seaver (sister to Tom, who went on to become a MLB Hall of Famer), and Cathy's mother sang "Scotch & Soda" to Dave.
Dave Guard wanted to sing it as a solo on The Kingston Trio's debut album for Capitol Records. Manager Frank Werber and possibly producer Voyle Gilmore as well,
felt "Scotch & Soda" was more suited to Bob Shane's voice.
Thus, not only did Bob Shane end up singing "Scotch & Soda" on the KT's first album; it became the #1 requested song at Kingston Trio concerts.
That's where the trouble started, and Dave Guard, being human, probably resented Bob Shane after that. Jealousy is as cruel as the grave.
Of course, Dave Guard had other issues too. As Joe pointed out, the $100,000 embezzlement, which was dismissed by Frank Werber (and laughed off by Nick & Bob).
Dave also was critical of Capitol Records photography for KT's album covers. He also became stressed out by the constant incessant traveling,
which as Dave Guard once put it: "made friendship a chore."
Ironically, Dave Guard wrote some of the liner notes for The Cumberland Three's first album: "Folk Scene U.S.A." going so far as to highly commend John Stewart
on his writing ability and tremendous talent!
Paul, just a theory:
When Dave fussed about the embezzlement of the publishing money and complained that he didn't think management was minding the store, he passed the point of no return with Frank Werber.
That was a direct challenge to Werber, and Werber made sure it was Dave, not Werber, who departed.
Some of Bob Shane's anger might be from an interview I remember where Bob says "Its too bad something couldn't have been worked out (with Dave) we were on a real roll !" Bob was thinking about all those years ahead that were thrown away by the split at the height of their popularity.
