Just to pick a few nits. The other Rodgers's name is spelled Jimmie [F] Rodgers, which is handy for writing and searching the net, but not for pronouncing.

In the 60s, folk programs tended to refer to Jimmie Rodgers (The singing brakeman, yodeler, etc) as the "legendary Jimmie Rodgers" to distinguish him from the more modern Jimmie.

CAUTION; The above was written by the world's worse speller!

One more thing. I was listening to an Ella Fitzgerald number called "Rock it For Me". She uses the phrase "Rock and Roll". This might be the first use of the phrase in a song. Unfortunately, it is a cheapie album, and they don't give recording details. The music bears no resemblance to Rock, R&B or Rock and Roll, by the way, and from it's style I would say it is made in the 40s.
