Lizabee,
Oats & beans & barley grow,
Oats & beans & barley grow
Do you or I or anyone know
How Oats & beans & barley grow

First the farmer sows his seed
Then he stands and takes his ease
Stamps his foot and claps his hand
And turns around to view the land

Waiting for a partner
waiting for a partner
waiting for a partner
So open the ring and let one in

Now you're married you must obey
You must be true to all you say
You must be kind, you must be good
And help your wife to chop the wood
Chop it thin and carry it in
and kiss your partner in the ring.

As it is in the book The Singing Game by Iona & Peter Opie. Hope this is how you remember it, we I seem to think did it a little different!
