Thanks for that info Jeannie. I'd love you to post that rhyme you mentioned your daughter doing. I think I know but I'm gonna hold off from guessing which song the rhyme came from.

Speaking of songs, there is another possible meaning of the word Gigalo/Jigalo. And this meaning could point to a source material for the rhyme. I'm wondering, could it possibly be that "Gingalo"/"Jigalo" is a variant form of the word "Jingalo"? I've read somewhere [??] that "jingalo" means "gypsy". I'd love to know if this is true, and if so which language does this word come from?

I'm wondering if it's too much of a stretch of credulity to think that a child in the USA or the UK or somewhere heard a cleaned up version {I hope} of @displaysong.cfm?SongID=2203 "Gently Johnny, My Jingalo".

And isn't it possible that some child liked the sound of the word "Jingalo" and made up a movement rhyme based upon that word?
And then isn't it possible that the word "Jingalo" would have been changed to "Jigalo" or "Gigalo"?

And is too much to speculate that over time, that this handclap rhyme became a handclap rhyme and then it became a footstomping cheer {since foot stomping cheers are a much newer form of children's performing art?}.

Again, we'll probably never know. But, it's possible, right?
