There is also a recording by Peter "Wyoming" Bender, alternately titled Wichi Tai To or Wichi Tai Tai. The best version of the lyrics I've come up by listening to it (plus a version I found on line) goes like this:

Wichi tai-tai,
Nee-mo-wah
Wo-rah-neeka, wo-rah-neeka
Hey-nay, hey-nay, no-way
Wichi tai-to,
Nee-mo-wah
Wo-rah-neeka, wo-rah-neeka
Hey-nay, hey-nay, no-way

Water spirits feelin', springin' round my head
Makes me feel glad that I'm not dead
