Here are the lyrics direct from The Weaver's Songbook:

Mi Caballo Blanco

by Francisco Del Campo, arranged and adapted by Erik Darling, Ronnie Gilbert, Lee Hays and Fred Hellerman

1. Es mi caballo blanco como un a manacer
Siempre juntitos vamos, es mi amigo mas fiel

chorus:

Mi caballo mi caballo, galopan do va
Mi caballo, mi caballo, se va y se va, Ah

2. En a las de una dicha, mi caballo corrido
En a las de una pena el tambien me llevo

3. Al Taiti Dios le pido y el lo sabe muy bien
Si a Su lado me llama en mi caballo ire

Translation:

1. My horse is fair as the dawn, always we go together
He's my most faithful friend, gallopong, he goes and he goes

2. On wings of joy my horse runs - and on wings of Sorrow,too, he carries me

3. I pray to God, and well He knows,
If He calls me to His side On my horse I will go
