There's the standard version:English country garden:
ENGLISH COUNTRY GARDEN

How many kinds of sweet flowers grow
in an English country garden?

We'll tell you now of some that we know
Those we miss you'll surely pardon
Daffodils, heart's ease and flox
Meadowsweet and lady smocks
Gentian, lupine and tall hollihocks
Roses, foxgloves, snowdrops, blue forget-me-nots
in an English country garden.

English country garden.
How many insects come here and go
in an English country garden?
We'll tell you now of some that we know
Those we miss you'll surely pardon
Fireflies, moths, gnats and bees
Spiders climbing in the trees
Butterflies drift in the gentle breeze
There are snakes, ants that sting
And other creeping things
in an English country garden.

English country garden.
How many songbirds fly to and fro
in an English country garden?
We'll tell you now of some that we know
Those we miss you'll surely pardon
Bobolink, cuckoo and quail
Tanager and cardinal
Bluebird, lark, thrush and nightingale
There is joy in the spring
When the birds begin to sing
in an English country garden.

How many kinds of sweet flowers grow
in an English country garden?
We'll tell you now of some that we know
Those we miss you'll surely pardon

Roses, foxgloves, snowdrops, blue forget-me-nots

What do you do when you can't find a Loo
In an English Country Garden?
Pull down your pants and fertalize the plants
In an English Country Garden.
