When I was in college I had a friend named Doug Quine (who last I heard was an evolutionary biologist in Nova Scotia and an expert philatelist), whose father, W. V. Quine, is (was?) a world renowned Harvard professor of mathematical philosophy. Doug told me that his father used to say that Tom Lehrer was the only person who ever received an A from him who did not go immediately into academics. (Preferring the bright lights and big money of show biz, of course.)

Tom was also one of Sesame Street's songwriters (which accounts for the classics "Silent E" and "LY"), and I think those songs came after 1965. But I could be wrong.

Aloha,
