My Dad sang a song to me when I was a boy (in the 60's), which in turn his father sang to him when he was small (in the 30's) which must have some relationship to the above lyrics:

King Arthur was King David's son,
And all the royal race was one,
Upon his head he wore a star,
A pointing the way to the pickle jar.

(and so on, I don't remember the rest)

Has anyone every seen/heard this version?
