This is from a song by Garth Brooks called The Cowboy Song:
Pushing horns weren't easy like the movie said it was
And I don't recall no dance hall girls
Or hotel rooms with rugs
You worked hot and tired and nasty
Rode your pony's head too low
There were all the nights you couldn't sleep
'Cause it was too damn cold
And you'd sing "Strawberry Roan" and "Little Joe"
Can anybody tell me what "pushing horns" refers to, and possibly the name of the movie in question as well?
