If I hadn’t picked such a classy name, I might have gone with:
Smoke Stack Lightnin’
Dust My Broom
Blues Walking Like A Man
That Spoon
Terraplane Blues
Crossroads
Yours?
Blind Cecil Doperman
Another Mule Kickin’ in Yo Stall
Well, that one’s kind of long.
Play wit’ yo’ Poodle
Born Under a Bad Sign
One would assume that **Back Door Man **would be an interesting username…
King Bee?
Crawling Kingsnake?
Hootchie Cootchie Man?
One that is less boasty but no less bluesy would be **The Stumble **- a truly great Freddy King track that would send a message of blues love balanced with a little self-deprecating humor…
Bleeding Gums Murphy
Asleep in the Desert

I am Sleepy Sugar Parker, which might be the most appropriate name imaginable for a diabetic saxophonist.
Hound Dog Taylor
I’m Fat Gumbo Jones. I like it, but as a user name I’d go with Fat Gumbo.
Wang Dang Doodle
Blind Lemony Snicket
Limpin’ Leeeroy Jenkins
Deaf Luddy Beethodder
Led Belly
I’m Old Fingers McGee!
The calculator says I’m Jailhouse Sugar Hopkins. I don’t know when I’ve ever felt quite so depressed.
Outstanding choice. 
Gatemouth Scriv’ or Etta James Scrivener
Boney Harp Rivers, half-brother of Geraldo.
