Just got Walter Jekyll, 1904, Jamaican Song and Story, and found this, obviously a variant of "Brown Gal in de Ring." :

CIX
There's a black boy in a ring,
tra la la la la,
There's a black boy in a ring,
tra la la la la
He like sugar an' I like plum.

Wheel an' take you pardner, jump shamador!
(3x)
For he like sugar and I like plum.

The boy inside the ring chooses his partner, whom he leaves there after the dance. She obtains release by choosing another partner, whom she leaves behind. So there is alternately a boy and a girl in the ring.
"Shamador" is possibly a corruption of "camerado."

With musical score, the first part of which is used in the story of Annancy and Screech-owl.

A variant of the Colon rhyme, and possibly others, are in this excellent book, reprinted by Dover.
