This is a handkerchief dance. Sharp and Macilwaine write:

 At Salperton [in Gloucestershire] the Morris men used to sing the following words:<\p>

Her feet were cold,
Her hands were warm,
But her heart was chilled
In many a storm.

Her head was right
But her heart was wild,
And he never came back to claim her.

At Ducklington [in Oxfordshire] the words were:

I can whistle,
And I can play,
And I can dance
The Shepherd’s Hey.

(Sharp & Macilwaine 1912, pp. 38-39)

They also tell us: “This air bears some resemblance to ‘The Faithful Shepherd’ in Thompson’s Complete Collection of Country Dances (circa 1775), which is reprinted in Mr. Kidson’s Old English Country Dances, p. 10.”

 [Fiddler’s Companion:]

English Morris Dance Tune (4/4 time).

The Shepherd’s Hey is the name of several variations of a dance popular among Cotswold morris for full teams or as a morris jig for three men; in fact, it is probably the most famous morris dance melody and can be found in various forms throughout England. During the dance the dancer keeps patting himself on the cheeks, breast and legs “in a most curious way.” One of the most widespread of the Cotswold morris melodies. The following ditties were sung during the dance, the first at Adderbury:

Shepherds’ Hey, clover too,
Rye-grass seeds and turnips too.

and at Bucknell:

One can whistle, two can play,
Three can dance the Shepherds’ Hey.
