You may be thinking of "Kookaburra sits in an old gum tree... "etc.  
Kook-kook-a -burra is a different one again, where you mimic the sound of the kookaburra's call while you sing the song: it's from Playschool originally, but I've only heard it a couple of times.  But it's now a favourite in my preschool!  I'll be walking around the playground with like a comet's tail of two or three classes, all of them making the kookaburra's call while I sing the verses!  

"Kook-a-kooka-burra, cack-a-cack-cackling
In the coo-coo-coolabah tree!
Kook-a-kooka-burra, ca-ca-can you tell me
why you cack-a-cack-cackle
coo-coo-coo-constantly?
etc. ad infitum..."

And when it's finally finished there's usually a chorus of four and five year olds saying: "More, please Ali?  More?"

It's very flattering, but hard on the voice!
