My Mom used to sing a song to me. I asked her about it & she sent me the words. The "kiss kiss" parts are a kissing noise, and the "waaah waaaah" parts are supposed to sound like a baby crying.

The Cannibal king with the big nose ring
Fell in love with the dusky maid
And every night in the pale moonlight
Across the bay he came.

He hugged and he kissed his pretty little miss
Underneath the bamboo tree
And every night in the pale moonlight
It sounded like this to me:
A-boom kiss kiss! a-boom kiss kiss!
Underneath the bamboo tree
A-boom kiss kiss! a-boom kiss kiss!
Underneath the bamboo tree

The years went by a-one two three
And soon they had a family
And every night in the pale moonlight
It sounded like this to me
A-boom waaah waaah! a-boom waah waah!
Underneath the bamboo tree
A-boom waaah waaah! a-boom waah waah!
Underneath the bamboo tree.
