That's a good story kat. And here is a good song about a horse that isn't on the DT, and seems fitting:

True you ride the finest horse I have ever seen,
Standing sixteen, one or two. With eyes wild and green,
And you ride the horse so well, hands light to the touch,
I could never go with you no matter how I wanted to.

CHORUS (Two times)
Ride on, see you, I could never go with you
No matter how I wanted to.

When you ride in to the night without a trace behind,
Run your claw along my gut one last time.
I turn to face an empty space where once you used to lie,
And look for a spark that lights the night
Through a teardrop in my eye.^^
