The tune, called by Marais a "veld song," was sung by soldiers on both sides during the war. Marais said "I wrote English verses and a definitive musical adaptation, which, to my delight, has captured..."
His verses were "I'm with you ...," "Sing with Me...," and "We have food n' ...," When we eat we will sing...," etc.

Anecdotally, Lord Baden-Powell on the march to Pretoria is supposed to have used the following, but this is mixed up with stories of Baden-Powell and Sgt. Major Goodyear and the founding of the Scouts:

March with me and we'll march together
And yes, we will march together (2x)
I'll march with you and you'll march with me
And yes, we will march together as we march.

Oh, yes, we're marching to Pretoria,
Pretoria, Pretoria.
We are marching to Pretoria,
Pretoria, Pretoria, hurrah!

One Boer version goes:

Jou kombers en
My matras en
Daar lê die ding,
Daar lê die ding,
Daar lê die ding.

(We are marching to Pretoria,
Pretoria, Pretoria.
We are marching to Pretoria,
Pretoria, here we come)

Die een kant op en
Die anderkant af en
Daar lê die ding,
Daar lê die ding,
Daar lê die ding.

This dance from Ralph Page, 1984, "An Elegant Collection of Contras and Squares," p. 15, Yates Publishing.

DANCING TO PRETORIA

Singing square. Song: Marching to Pretoria

Intro, Break and Ending
All join hands, circle left, circle once around
All the way around, 'til you get back home again
Reverse back, the other way you go then
Right hand to your partner for a grand right and left
[all the way around]; sing it!
We'll go dancing to Pretoria, Pretoria, Pretoria
We'll go dancing to Pretoria, Pretoria, hurrah!

Figure
Allemande left your corner and
Come back and swing your partner
Swing with your partner, swing around and round
The head two couples right and left through
Turn to face back in
And the side couples do the same old thing
Then you promenade one-quarter way round the ring
Four ladies chain, chain across the ring
Then you chain right back and with your partner swing
To Pretoria, hurrah!

Sequence: Intro; figure twice for heads; break; figure twice for sides; ending.
