The meticulous Yale Book of Quotations credits Legman with coining the phrase, "Make love, not war."
Back in the '70s, I sent Legman the text of "The Rover" that he prints as a forerunner of "The One-Eyed Riley." (I also helped him verify Mark Twain's verse about impotence.) Judith Legman could not have "destroyed" his folklore collection: she helped him collect it!
Somebody may be thinking of Sir Richard Burton's papers, allegedly destroyed by his wife back in the Victorian age.
Then there's the question what (if anything) may have happened to Stan Hugill's uncensored collection of shanties.
