I've found an English version, but I don't know whether it is a translation or a singable one:

Sarie Marais
(South Africa)

My Sarie Marais is so far from mh[sic] heart,
but I hope to see her again.
She used to live near the Mooi river
before the beginning of the war.

Oh bring me back to the old Transvaal,
there where my Sarie lives,
down there in the mealie fields by the green thorn tree,
there my Sarie Marais lives.
