Cowboy Clunkies

Here's what the cowpokes were singing (and it might help to tell you to sing it using only two or three different notes, kind of speak-singing):

In the wild west, there were cowboys who rode on horses.
On the prairie, they roasted hot dogs -- and marshmallows too-oo-oo.
In the wild west, there were cowboys who rode on horses.
On the prairie, the cowboys fought all night -- and all day.
In the wild west, in the wild west, in the wild, wild, wild, wi-i-i-ld west.
