...to clarify the language of Blues lyrics:

I Have A Little Girl by Howlin' Wolf:

I got a little girl
All eighteen years old

And if you say "Sonny Boy Williamson", you should also say which Sonny Boy Williamson you are talking about; there were two famous blues singers of that name.

Songwriting credits on early and classic blues songs ahould be taken with more than just a pinch of salt, anyway. Howlin' Wolf used to claim that the classic songs that Willie Dixon had written for him (Spoonful, The Red Rooster, Backdoor Man and others) were really written by the legendary Charley Patton back in the 1920s.

And none of the so-called "artists" you mention are in the league of the true blues artists they stole their music from.
