One we used to sing in the Scouts.

Ging Gang Gooly Gooly Gooly Gooly Watcha
Ging Gang Goo, Ging Gang Goo.
Repeat
Hayla, Hayla Shayla, Hayla Shayla Hayla Ho
Repeat
Shalli Walli, Shalli Walli, Shalli Walli
Oompah, Oompah, Oompah, Oompah.

Total nonsense words as far as I am concerned, but I suspect derived from something in an African Language as Baden Powell spent time in Africa.
