Note the pedal D in the verse (both under the D Major and C Major chords). The chorus cleverly modulates to the key of a (IV - I - V).
[Verse]
In her past there's lots of people
I know them by their names
Some of them rushed by like water
And some of them were flames
[Pre-Bridge]
Each and all knew a different girl
Someone I never met
But with her parties
Good times she won't forget
[Bridge]
And here I come with empty hands ready to receive
And I just hope she doesn't change her mind and want to leave
[Chorus]
Oh, girl, stay right with me
I's gonna get better eventually
Oh, girl, stay with me
It's gonna get better eventually
[Verse]
I came along when she had offers
Offers left and right
I gave her all I had to give
All my best in sight
[Pre-Bridge]
But now she knows the uselessness,
The nonesense of it all
Oh, she understands the ways of men
Kicking in their stall
[Bridge]
And here I come with empty hands ready to receive
And I just hope she doesn't change her mind and want to leave
[Chorus]
Oh, girl, you got to stay with me
I'll get better eventually
So girl, please stay right here with me
You'll see a change comin' over me
[Interlude]
And some times when I look at her I see a different girl
I wonder what she's thinking and if she is not all of my world
[Verse]
I've got the feeling that I've done harm,
No good there have I done
I see a nervous stress that onece was mine
Of which she asks for none
[Pre-Bridge]
And here I come with empty hands, I'm ready to receive
And I hope that she doesn't change her mind and want to leave
[Chorus]
Girl, you got to stay here with me
Things are gonna get better eventually
Girl, please stay with me
I feel a change comin' over me
Girl stay with me
I feel a change has to be
Oh, please stay with me
This are gonna get better eventually
