Anybody remember 'This Little Song'?

It featured Shari and the kids (with the usual current-day sound-sweetening to force the kids to sound like they were singing in harmony. In a tin can. But it worked in a particularly haunting, eerie way in this song) making sounds animals make, like this verse

Shari:
This little song is sung by a duck,

it goes quack quack quack quack, quack-quack, quack-quack.

This little song, is sung by a duuuuuuck...it goes

Kids and Shari: quack quack quack quack, quack-quack, quack-quack.

I can't find it on any amazon.com Shari Lewis/Lambchop albums. Does anyone remember this song from the show, and know where I can find it?
