From my research, it is a Maori song from New Zealand and the words I recall singing were:
    Ma Koo Ay
    Ko Tay O
    Ay Koo e Tah no....
We held Lemmi/Lummi Sticks in each hand and beat the sticks on the floor, against each other and twirled them around to the beat of the music. I just listened to the song when I went to Amazon.com to a book of Maori songs but now I can't locate the book! Anyway, I hope this helps. If anyone can find the song or a video of the song with the lemmi/lummi sticks, please let me know.
