I would be interested to know whatever happened to Mike Pugh and David Boise. Pugh was the original baritone in the Chad Mitchell Trio, appearing on their debut album and their guest shot on "Belafonte Returns to Carnegie Hall" before leaving the group and being replaced by Joe Frazier. Boise actually replaced Joe Frazier at the end of the Trio's run, joining Mike Kobluk and John Denver on the Trio's final album. He later was part of the short-lived Denver, Boise and Johnson (that would be Michael Johnson, who's had quite a distinguished career since the 60s).
