Life on Mars?

A very lovely melody with mad lyrics from David Bowie. I liked the melody so much I went to look for the lyrics, but a whole different lyrics appeared on screen. Did he write two songs with the same title. Apparently he did, he wrote a gorgeous love song along the musique of French song "Comme d'habitude", better known in America for the Elvis/Sinatra version "I did it my way".

The hand that wrote this letter
Sweeps the pillow clean.
So rest your head and read a treasured dream.
I care for no one else but you.
I tear my soul to cease the pain.
I think maybe you feel the same,What can we do?
I'm not quite sure what we're supposed to do.
So I've been writing just for you.
They say your life is going very well.
They say you sparkle like a different girl.
But something tells me that you hide
When all the world is warm and tired.
You cry a little in the dark,Well so do I.
I'm not quite sure what you're supposed to say,
But I can see it's not okay.
He makes you laugh
He brings you out in style.
He treats you well
And makes you up real fine.
And when he's strong,
He's strong for you.
And when you kiss
It's something new.
But did you ever call my name
Just by mistake?
I'm not quite sure what I'm supposed to do.
So I'll just write some love to you.

However, the super lovely melody with the same song title by the same artisit has much more morose lyrics to it: but if you close your mind and just listen to the music, it takes you on a magical journey to Mars.

It's a God awful small affairTo the girl with the mousey hair,
But her mummy is yelling, "No!"And her daddy has told her to go,
But her friend is no where to be seen.
Now she walks through her sunken dreamTo the seats with the clearest view
And she's hooked to the silver screen,But the film is sadd'ning bore
For she's lived it ten times or more.
She could spit in the eyes of foolsAs they ask her to focus onSailorsFighting in the dance hall.
Oh man!Look at those cavemen go.It's the freakiest show.
Take a look at the lawman Beating up the wrong guy.
Oh man!Wonder if he'll ever know He's in the best selling show.
Is there life on Mars?
It's on America's tortured browThat Mickey Mouse has grown up a cow.
Now the workers have struck for fame'Cause Lennon's on sale again.
See the mice in their million hordesFrom Ibeza to the Norfolk Broads.
Rule Britannia is out of bounds To my mother, my dog, and clowns,
But the film is a sadd'ning bore'Cause I wrote it ten times or more.
It's about to be writ again As I ask you to focus onSailorsFighting in the dance hall.
Oh man!Look at those cavemen go.It's the freakiest show.
Take a look at the lawman Beating up the wrong guy.
Oh man!Wonder if he'll ever knowHe's in the best selling show.
Is there life on Mars?

... and I wonder why David put such ugly lyrics on this beautiful melody, but I guess it's the madness that usually accompanies genius.
