"The chickens are revolting"!! No, no, no!
Seriously? Hm. I'd want a mix of my favorite Jerry Goldsmith Western soundtrack cues, as well as a few of my favorite opera arias. But the big ones would be Rio Conchos, Breakheart Pass, Take a Hard Ride, 100 Rifles, Bandolero, The Loner, Rio Lobo, Hour of the Gun, Lonely are the Brave.
Or this works rather nicely! Hits most of the main themes, anyway!
