The one I know is very close:
I used to have an old gray mule, weighed 1500 pounds.
Every tooth in that mule's head was 13 inches round.
Whoa, mule, whoa! Whoa, mule, stay!
I ain't got time to kiss you now. my mule's running away.
Grandpa rode that old mule, rode her into town.
Before he had her cross the creek, the buzzards had him down.
Now Peter was a big old boy. Peter wasn't stout.
Then Peter took the measles, and Peter petered out.
I used to have an old banjo all strung up with twine.
The only song you'd hear me sing is "I wish that girl were mine."
