On YouTube, there's an Edison cylinder recording from between 1912 and 1917 of "Way Out West". This puts some question on the attribution of the song to Robison, or at least puts the 1924 origination date earlier--notably, the work is clearly in the public domain.

In that version (leeneia will be relieved to know), the couple verse is particular to a single couple--and we all know at least one such.
