The song I'm All Behind You Know is performed by George Strait .
Leavin' me behind is all behind you now
It's plain to see that you're for good over me
You've gotta whole new life ahead of you
You did what you lived to do
And I'm all behind you now
And I'll be behind you always
Should you every be a yesterday
Though it tears me up
To know deep down
I'm all behind you know
You're comin' back
My way will come my way again
I'll never be what I was with you and me
And I don't know who or where your goin' to
But you did what you lived to do
And I'm all behind you now
And I'll be behind you always
Should you every be a yesterday
Though it tears me up
To know deep down
I'm all behind you know
Yeah it tears me up to know deep down
