All of the above are accurate in some context. However, if you are asking about the song with the line "C. C. Rider, see what you done done, You made me love you, now your man done come" none apply. I am hoping much of the above was collective pulling of the leg.

I have heard that the term C. C. Rider is a corruption of the term "easy rider" which referred to a woman with whom one has casual sex. Using that definition, the above line makes some sense. I am sure it has nothing to do with motorcycles since the song surely predates the internal combution engine. There may, however, be some connection with the Railroads. There were a multitude of little Railroad companies throughout the South. They were fairly independent and might only serve between two major cities. Different companies often did not share railways. There was no standard track gauges, so cars from one company often could not fit on the track of another company. This drove the armies crazy during America's Civil War. You'd transport the troops to one city and to get to the next one you may have to unload them, march them to another railroad in the town and put them on rail cars again. How inefficient. Later monopolies (and the utter destruction of the Southern rail system) helped lead to standardization.

Well, that's a long way from C. C., but them's my words and I'm stickin' to 'em.
