Thanks for posting that, Jon. It's the first version from Canada. Nor does the song appear in any military songbook I know of.

An earlier reference:

York [Pa.] Daily (Dec. 6, 1907): “It must be admitted that the difficulty lies in finding those [‘cow puncher songs’] ‘fit for publication.’ Many of them, like ‘The Red Light Saloon,’ are exceedingly frank in expressing the opinions and elemental desires of the animal man. The songs that won most applause of nights on the ‘round up’ wouldn’t look well in print. But…a few…are proper enough.”
