CAIRO BLUES
As recorded by Melvin "Lil' Son" Jackson on Gold Star 663, 1949 (~2:31).

You know I want to go to Cairo but the water's all over town. (2x)
The polices on the corner don't 'low nobody round.

Cairo, Cairo is a place I dearly love. (2x)
Ev'rything around me with the moon and stars above.

Break

You know I'm ragged and dirty, been barefoot and hungry too. (2x)
Well, if I clean up, baby, can I go home with you?

Well, I love Cairo, boy; back there I'm goin' to stay. (2x)
Well now, bye-bye, baby, right now I'm on my way.
