I never agreed with the last verse. Of the four characters (Frankie, Johnny, Nellie Blye, and The Warden) only the Warden didn't cheat or murder anybody. And he's a man. So what the heck?
I have observed since then, that "cheating" always involves two cheaters, one of whom is usually a woman. I have also observed that women sometimes cheat with other women ...
Some women who cheat get wacked, too.
Good point. However, the lyrics are what they are.
I have several Kingston Trio LPs, but I don't seem to have that one. I got the lyrics from a book of American folk songs.
