Merci, Stewie. I read that entire thread -- and I'm still in the dark. I'm trying to get the history of the apparent existence of two Jimmie Rodgers versions with completely different lyrics: "Ramblin' Bob" and "Cambell". As someone pointed out in THIS thread, Jimmie Rodgers recorded a "Jailhouse Now" No. 1 and a No. 2. Are these the two different versions we're talking about? Number 2 doesn't refer to the "Jailhouse Blues" does it?:

Nobody here can sing the jailhouse blues
'Till you've been behind four walls.
...etc.

I've only actually heard Jimmie singing the "Cambell" version -- and everybody else in the country field singing the "Ramblin' Bob" version.

Still waiting for clarification, I remain,

James.
