[Verse 1]
 
Is it wrong to call your name
 
On the Apalachee Plain?
 
When I know it’s been called
 
A thousand times
 
If at all
 
Is it wrong
 
To call your name
 
Once again?
 
 
Wishing’s easy
 
If you try
 
Don’t get bogged down
 
And don’t you cry
 
If it comes true
 
So be it
 
And if it don’t, just believe it
 
To be the way
 
That it always
 
Ought to be
 
 
[Verse 2]
 
Mustangs are kicking in the field
 
I saw it all behind the wheel
 
But it woulda never had that feel
 
If you weren’t right there at my heels
 
Holding up
 
Your end of the bargain
 
 
So how about you lean on in
 
Just this one time give me that grin
 
The one I first saw laying in bed
 
With your hair about our heads
 
When the sky it was deserted
 
 
[Verse 3]
 
In the space of a couple lines
 
I'm reminded from time to time
 
You were in and throughout
 
Before the flood, before the drought
 
Before the sunlit garden grew
 
Before the ashes filled the tombs
 
No there ain’t nothing
 
I can change about me now
 
No there ain’t nothing
 
I can change about me now
 
No there ain’t nothing
 
I can change about me now
