When Ed McCurdy played I Cobourg, Ontario a couple of decades ago, he distributed the words to "Last Night I Had The Strangest Dream" and told the audience to note that he had changed, "And the room was filled with men," to, "Filled with women and men.

The person who wrote the words for Neil Armstrong to speak when he stepped onto the moon was pissed off at the fact that Neil left out a word which changed the meaning entirely - "One small step for (a) man; one giant step for mankind."

And regarding changing the sex of the character in the song to match the sex of the singer, many male sigers like Josh White, Woody Guthrie, Jack Elliott, Dave Van Ronk and Bob Dylan didnèt mean to mind singing the woman's part in "It's been the ruin of many poor girl, and me Oh God, I'm one," while Eric Burdon didn't feel comfortable singing the part of a woman trapped in a life of prostitution, so sang the part of a man trapped in a life of paying for sex (or perhaps a boy trapped in a life of prostitution). He sang, "It's been the ruin of many poor girl, and me Oh God, I'm one."
