Always loved his cover of this and no one else had put it up.  Should be 100%.

I do not mean you trouble, don't put me down, don't get upset
I am not pleadin' or sayin' I can't forget you
I do not pace the floor, bowed down and bent, but yet
mama you been on my mind

G & riff 2

Even tho' my eyes are hazy
and my thoughts they might be narrow
where you been don't bother me, or bring me down with sorrow
I don't even mind where you be wakin' up tomorrow
but mama you been on my mind

G (320003@1)I'm not asking you to say words like yes or no
Please understand me, I've no place I'm calling you to go
I'm just whisperin' to myself so I can pretend that I don't know
Mama you been on my mind

G C G C & riff 1

When you wake up in the mornin' baby, look inside your mirror
you know I won't be next to you, you know I won't be near
I'd just be curious to know if you can see yourself as clear
as someone who has had you on his mind
