I just re-read this thread and noticed that I didn't acknowledge or respond to English Jon's interesting comment that was posted on 16 Apr 07 - 08:39 AM.

Jon asked two questions that I'd love responses to:

"An interesting point would be, what is the earliest known usage of a version of this rhyme?"

and

"Gigalo (man) I'd always assumed was an american word - Do we know anything more about the origins of the british Jackalo?"
