My father carried the chorus all his life. His father was a mounted infantryman in that war. He was surprised when I found him the verses, but Cosmotheka had been played on the radio, and I'd recorded it.
Dad's version of the chorus was;

The baby's name is...
Kitchener Gatacre Methuen Crondell White,
Kronje Kruger Powell Majuga Gatacre Warren Colenso Buller,
Capetown Mafeking French,
Kimberly Ladysmith 'Bobs',
Union Jack, Fighting Mac,
Lyddite Pretoria... Blobbs.

Obviously something wrong there, Gatacre is repeated, but that was the chorus I sang, out of loyalty. And no-one sings along with you, anyway.
