The Dun Cow one we sang in Girl Guides was:

We are the red men, tall and quaint
With our feathers and war Paint

Pow wow, pow wow
We're the men of the Old Dun Cow
We are the red men
Feathers in our head men
Down among the dead men
Pow wow, pow wow

We come home from fighting wars
Greated by our long-nosed (long-necked?) squaws

pow wow etc...

I haven't heard it sung in years, certainly not in this era of political correctness.
