Songs that cannot be sung by just anyone, & songs with outdated references/meanings

[um]

"I am Woman" by Helen Reddy is an obvious one. Only female singers can sing it seriously.

There are songs in which the gender element can be reversed.

Killer Joe sung by the Rocky Fellers has it so that the singer is saying that Killer Joe is dancing with Marie and "He don't act like he knows, she belongs to me"
But I have heard a version in which the female singer is saying that Killer Joe is dancing with Marie but then the next sentence says, "Someone ought to tell her (Marie) , he belongs to me."

Sometimes singers just go ahead and use the original lyrics not changing the gender-based viewpoint of the singer. Joan Baez' "The Night They Drove Ol' Dixie Down" has her singing about being a man of the times of the railroad and pioneer times, but somehow it does not sound out of place. Maybe no other singer than Joan Baez could have done that. Actually, it is harder for a male singer to sing a song that is in the viewpoint of a woman than the other way around.
I have heard that the song "Danny Boy" is in the viewpoint of a female singing to a boyfriend of her's who is going off to war, and some male singers have sung the song Danny Boy, but I have heard that actually the song was originally written by a man saying goodbye to his son who is going off to war. I recall seeing comedian Danny Thomas on The Mike Douglas show (yes back in the 70s) explaining that the song was written by a man who already had three of his sons go off and be killed at war and he was now saying goodbye to his last son to go off to war and if his son does come back home, he may find that his dad had died already.
But some people have said that it is the girlfriend of the soldier departing to war who feels she may die waiting for him to come back.


Also I have thought about the song "Happy Together" originally by "The Turtles."
It has a verse saying "If I should call you up and waste a dime, and you said you belonged to me, I'd lose my mind."
It was written back in the 60s, but a phone call stopped costing a dime in the mid 1970s ( I think).
And still, even though pay phones are practically defunct, you can get the meaning. Of course I could be wrong. Maybe it is only people who were alive back in the 60s who can understand. Maybe young people born only 20 years ago cannot really perceive of a world like those of us who used to recall ten-cent pay phones.

Any other examples?
Thoughts?

I have read that the German metal band Accept had lyrics that many thought were "gay" in nature--until it was disclosed that the wife/girlfriend was the one responsible for writing the lyrics of the songs.
