Intro: A D
A E D
A D
Ive spent too long away from home
A
Did all the things I could have done
D
Gone are the days of endless thrills
A
I know Im not the only one
E D A
So long, Im goin, goin home
A D
I saw the streets all ripe with jewels
A
Balconies and the laundry lines
D
They tried to make me welcome there
A
But their streets did not feel like mine
E D A
So long, Im goin, goin home
A D
I want the sun to hit my face
A
Through oak trees in the open lot
D
Forget about the things you want
A
Be thankful for what all you got
E D A
So long, Im goin, goin home
