When you wake up in the mornin', baby, look inside your mirror
I won't be next to you, you know I won't be near
I'd just be curious to know if your reflection is as clear
As the one that I've got on my mind
Mama, you been on my mind

Well, perhaps it's the wind and the dark, dark night
That's coverin' the crossroads that I'm at
And maybe it's the weather or something like that
But, Mama, you been on my mind
Mama, you been on my mind
[ Lyrics from: http://www.lyricsfreak.com/j/johnny+cash/mama+you+been+on+my+mind_20803844.html ]
Well, I don't need trouble, please don't put me down
Don't get upset, I am not pleadin', I won't say I'll forget
And I won't pace the floor, bowed down and bent
But yet, Mama, you been on my mind
Mama, you been on my mind

Even though my mind is hazy and my thoughts are kinda narrow
Where you been, don't bother me or bring me down with sorrow
It don't matter to me where you'll be wakin' up tomorrow
But, Mama, you been on my mind
Mama, you been on my mind
