"(Honey Babe/Darling), you can't love one (x2), You can't love one and still have any fun, Honey Babe, you can't..." Similarly, "You can't love two and still be true..." "You can't love three and still have me..." Etc.
"Honey Babe" and "New River Train" are two versions of the same set of verses, the difference being that the latter has a chorus about the "New River Train" ("Riding on that new river train (x2), Same old train that brought me here Is soon gonna carry me away").
It's not clear which is the original form, but I'm guessing the former. - RBW
Well, [you] may be wrong here; the "New River Train" version dates back to at least 1924 (Whitter's recording). And Fields Ward says he learned it c. 1895. - PJS
In any case, "New River Train" is now the more familiar version (see the recording list), so I eventually adopted that title.
Cohen has notes about the origin of the name "New River Train"; there apparently was no line with that name, but several railroads had track in the New River area and would presumably have been given that name informally. What's more, the earliest recordings he cites (Whitter's and Harrell's) are by residents of that part of Virginia. Vernon Dalhart's recording was similar to and likely based on Harrell's, and that no doubt helped put the song in popular consciousness.
Cohen does report, however, that few versions other than Ernest Stoneman's have much real railroad content. That is the main reason why I thought (and still sort of think) the versions without the New River Train chorus likely to be original. - RBW
