From the Mainly Norfolk site;

There was a jolly plooboy, a-plooin up his land,
He whistled and he sang all day to make the valleys sound,

Singin tarry doodle aye, doodle aye, doodle aye,
Tarry doodle aye ae
Tarry doodle aye, doodle aye, doodle aye,
Tarry doodle aye ae.

The nuts that she was gaitherin, she threw them aa away,
She went tae hear the plooboy sing, Tarry doodle aye ae.
