Over the years I've had no luck locating a recording of a song that might be titled "Horse Trailer on a Cadillac"/"You're Talking to the Cowboy in the Coupe de Ville", or even any evidence that it existed. It was on a homemade compilation of songs performed by the Nitty Gritty Dirt Band. (I borrowed this one from a different boyfriend in the mid-1980's!)

Y'all (Peace, actually) just helped me track down a folk song I told a similar tale about--so here goes: These are all of the lyrics that I can currently remember (includes some mistakes):

Refrain:
10-4, buddy, come on back, horse trailer on a Cadillac,
You're talking to the cowboy in the Coupe de Ville
Chug a lug up one side, fly down the other
I'm a lover of the other side of the hill

That's what my daddy told me
How to ride the bull
Got a jingle in my jeans
Sore places in between
I'm leavin' Tennesse
With a [purse and bull]

. . .
Jump while he's moving
Just walk away
. . .

Turn up that radio
And don't think about rodeo
Don't think about Roundup
Up in old Cheyenne
It's a crazy circuit
But you still work it
Just turn the sound up
Let's check the scan
