I have no idea where
Cornelius Neitsch obtained the text and tune for his SATB arrangement of
Epo i tai tai eh! which he wrote in 1992 and may be found in the
Neitsch Folio. His notes erroneously ascribe its origins to "Gesang nach erfolgreichen Fischfang - trad Maori-Westaustralien" somewhat to the wry amusement of my Maori acquaintances. I wonder if Neitsch was aware of its bawdy misuse by New Zealand servicemen!
That being said I greatly enjoyed singing it with the
DOKU-Chor and later introduced it to the
The Vegesack Whalermen.
