This is the regimental song of the 3d ACR(Brave Rifles) and, according to their unit history, here are the lyrics

I left my loves a letter in the holler of a tree
I told 'em they could find me in the U.S. Cavalry
    (CHORUS)
Hi Ho, off we go, a never-ending story
We'll ride right through to Hell! and Back!
And grab the reins of glory

I left my my love, my love I left a sleepin in the bed
I left the side of my true love to fight until I'm dead

       CHORUS

In eighteen hundred forty six the call to war began
A regiment of mounted men, of mounted riflemen.

          Chorus

From Mexico, our first campaign, and through the civil war
As Patton's lead, our country's need, and back from Saudi's shore

            chorus

The sun may set on all the rest, but they can never be
BRAVE RIFLES, VETERANS! BLOOD AND STEEL,
THE BEST OF CAVALRY!


Hi ho, off we go, a never-ending story
We'll ride straight through to Hell! and Back!
And grab the reins of glory


To any Brave Rifles who may see this   AIEEYAH!!!! from a cavmom
