The relevant passage is quoted at the Fiddlers Companion (see Sorcha's post), together with a good bit of further information precied from various sources. In a box somewhere, I have a collected edition of all the Spectator pieces; but they don't have anything to do with the dance, of course.

The tune appears in the Dancing Master (1695 and thereafter), first in 3/9 and later in 9/4. Notation and dance instructions are at The Dancing Master, 1651-1728: An Illustrated Compendium
