You probably mean this song. I've also included a similar song that The Watersons sang, The Brave Ploughboy

ALL JOLLY FELLOWS THAT FOLLOW THE PLOUGH

It was early one morning at the break of the day;
The cocks were a-crowing. The farmer did say:
'Come arise, my good fellows, arise with goodwill,
For your horses need their bellies to fill'

When four o'clock comes round we hastily rise
And into the stable we merrily fly
A-brushing and a-rubbing away we do go,
For we're all jolly fellows that follow the plough.

When six o'clock comes round at breakfast we meet;
We sit round the table and heartily eat.
A bit in our pocket and away we do go,
For we're all jolly fellows that follow the plough.

The farmer comes round; as he does he will say:
'What have you been doing all on this fine day?
You haven't ploughed one acre, I'll swear and I'll vow.
You're all idle fellows that follow the plough'.

Our carter stepped up and he made this reply:
'What you have said is a jolly big lie.
We've all ploughed one acre, I'll swear and I'll vow.
We're all jolly fellows that follow the plough'.

The farmer turned round and he laughed at the joke.
It's gone two o'clock, lads, it's time to unyoke,
Unharness them 'osses and rub them down well,
And I'll bring you a pint of my very best ale'.

THE BRAVE PLOUGHBOY

Come all ye jolly ploughboys and listen to me lays
And join with me in chorus, and I'll sing the ploughboy's praise
My song is of the ploughboy's fame
And unto you I'll relate the same
He whistles, sings, and drives his team, the brave ploughing boy.

So early in morning, the ploughboy he is seen
He hastens to the stable, his horses for to clean
Their manes and tails he will comb straight
With chaff and corn he does them bait
And he'll endeavour to plough straight, the brave ploughing boy.

Now all things being ready and the harness that's put to
All with a shining countenance his work he will pursue
The small birds sing on every tree
The cuckoo joins in harmony
To welcome us as you may say, the brave ploughing boy.

So early in the morning to harrow, plough, and sow
And with a gentle cast, me boys, we'll give the corn a throw
Which makes the valleys thick to stand
With corn to fill the reaper's hand
All this, you well may understand, comes from the ploughing boy.

Now the corn it is a-growing, and seed-time that's all o'er
Our master he does welcome us and unlocks the cellar door
With cake and ale we'll have our fill
Because we've done our work so well
There's none here can excel the skill of the brave ploughing boy.

Now the corn it is a-growing, and the fields look fresh and gay
The cheerful lads come in to mow, while damsels make the hay
The ears of corn they now appear
And peace and plenty crowns the year
So we'll be merry whilst we are here, and drink to the brave ploughing boy.
