Dan,

Even after my longest search so far, I haven't come up with anything on this song. I found a song called "Lonesome Dog Blues" by Lightnin' Hopkins--but that's not it. So I posted a question to some guy who has a blues lyrics website and also, on a thread on a blues forum. They will respond to me via e-mail so if I hear from anyone, I'll let you know. (sigh)
