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
