The Muddy Waters version was originally recorded in 1951 under the title "Still A Fool". Thans to Anita Cantor for alerting me to this, and pointing me to a Rob Quinn transcription of the lyrics. According to Anita, Muddy Waters also recorded it with different lyrics under the title "She's All Right"

The Muddy Waters lyrics are:

Well now there's two
There's two trains runnin'
Well ain't not one, (ho!) goin' my way
Well now one run at midnight
And the other one runnin' just 'fore day
A runnin' just 'fore day
It's runnin' just 'fore day
Oh Lord
Sure 'nough then
Oh well

Hmm, (ho) (ho)
Somebody help me (ho) with these blues
Well now, she's the one I'm lovin'
She the one I do hate to lose
I do hate to lose
I do hate to lose
Oh Lord
Sure enough I do
Oh well

I been crazy
Yes I been a fool
I been crazy, oh all my life
Well I done fell in love with her
With another man's wife
With another man's wife
With another man's wife
Oh Lord
Sure 'nough I done
Oh well

Long, she's long and tall
'Til she weeps like a willow tree
Well now, then say she's no good
But she's all right
She's all right with me
She's all right
She's all right
She's all right
She's all right
