Here's a tune for this - one of many tunes, no doubt:

http://www.traditionalmusic.co.uk/song-midis/Wraggle-Taggle_Gypsies.htm

The unabridged dictionary says that 'wraggle' is a variant of 'wrangle.' That would be suitable for gypsies, who often were in the horse trade.

'Taggle' is an archaic word meaning to tag or to follow.

And here all these years I thought 'wraggle taggle' referred to their ragged appearance.

By the way, just the other day I referred to the woman in my church who lures lost cats in and finds homes for them as a 'cat-wrangler.'
