Adjetivo depois do sujeito

Olá pessoal, sei que no inglês, usamos o adjetivo sempre antes do sujeito, mas esses dias estive observando uma música "Girls Just wanna have fun", e notei que algumas partes ela usam o adjetivo depois do sujeito.

I come home in the morning light
My mother says when you gonna live your life right
Oh mother dear we're not the fortunate ones
And girls they wanna have fun
Oh girls just wanna have fun

The phone rings in the middle of the night
My father yells what you gonna do with your life
Oh daddy dear you know you're still number one
But girls they wanna have fun
Oh girls just wanna have--

That's all they really want
Some fun
When the working day is done
Girls-- they wanna have fun
Oh girls just wanna have fun

Some boys take a beautiful girl
And hide her away from the rest of the world
I wanna be the one who walks in the sun
Oh girls they wanna have fun
Oh girls just wanna have

That's all they really want
Some fun
When the working day is done
Girls--they want to have fun
Oh girls just want to have fun,
They wanna have fun,
They wanna have fun...

Alguém pode me dizer se a maneira com ela escreveu a música está errada?
ou existe um exceção para o DEAR?
