This is a relatively innocent version:

Lyrics from The New Standard Song Book, edited by J. E. Carpenter (London : G. Routledge & Sons, 1866), page 82:


THE CARMAN'S WHISTLE.
[Tune—"The Carman's whistle." 16th Century.]

Young Tom the carman's tongue was slow,
A sorry gift of speech had he;
He'd rather let his horses know
His secret thoughts than you or me.
He whistled, whistled, whistled daily,
Whether good or ill befell;
He whistled sadly, whistled gaily,
While his horses marked him well.

Fair Susan's glance was proud and cold,
The carman's heart she nearly broke;
But still his face was bluff and bold,
And not a single word he spoke.
He whistled, whistled, whistled sadly,
Whistled, whistled all the day;
But though he whistled, whistled madly,
Could not whistle care away.

Fair Susan's glance was kind and bright,
She owned her love, that buxom maid;
Young Tom was crazy with delight,
He stammered, blushed, but nought he said.
He whistled, whistled, whistled gaily,
His joy by whistling he would tell,
And while he whistled, whistled daily,
The knowing beasts rejoiced as well.
