Thanks for the link Jim. Nice bio of Bob on page 123 (58 of 58). Although I question “The group never wrote its own songs” statement. The bio even mentions John Stewart in the next sentence.
Bob's death is mentioned in passing on page 5 here under Class of 1952. My link opened to the class of 1946, whose secretary is Bud Schoen, Bob's brother who friended me on FaceBook after Bob's passing.
