In my Brownies (which was only the 90s), I was taught:

KOOKABURRA

Kookaburra sits in an old gum tree
Merry merry king of the bush is he
Laugh, kookaburra, laugh, kookaburra!
Gay your life must be!

Kookaburra sits in an old gum tree
Counting all the monkies that he can see
Stop, kookaburra! stop, kookaburra!
Please do not count me!

Kookaburra sits on electric wire
Tailfeathers burnt and his bum's on fire
Ouch, kookaburra! ouch, kookaburra!
Burnt your bum may be!"

There were other verses, I think, and I'm not sure it was 'ouch, kookaburra' in the 3rd verse, but my version was definately 'tailfeathers burnt' not 'tears in his eyes'...
