I just sang my version on the Singaround. Everybody else was singing long, long songs that made mine seem too short, so I wrote a new verse on the spot. Here's verse 4

At night, when it's dark on the prairie,
I count every heifer and steer.
I sing to the poor little dogies
so they know that their cowboy is near.

A dogie is an orphaned or neglected calf.

The original says "Get your name in the great tally book." That makes me think of the poem about Abou ben Adhem.
