We sang this song in Durham / Northumberland UK in the late 50's early 60's. The verses were;

There was a Bog, a rattling bog
and in the bog there was a tree
and on the tree there was a Limb
And on the Limb there was a Branch,
On the branch there was a twig
On the Twig there was a Nest,
On the nest there was an egg
On the egg there was a lion, (Lions were printed on eggs in the UK at that time)
On the lion there was a bird
On the bird there was a feather
From the feather they made a bed
On the bed there was a maid
On the maid there was a man
From the man there came a seed
From the seed there came a tree
