I wrote this in the 1960s .. what a pedigree! (melody the wearing of the green)

Chorus:
Oh it is the greatest mix up,
That I have ever seen,
His father is a German and his mother is a queen.

He is the prince of Wales although he's England's future king,
And his granny is the daughter of a Scotchman's highland fling.
His aunt in Holland is the niece of Norway's royal pair
And if they all died in their beds he'd be the Belgian heir.

His father's mother came from Greece, his aunt's Bavarian,
Himself he wears the tartan of the Royal Stewart clan.
His second cousin's Danish, at least what he thinks
For surely Queen Victoria must be the missing link.

His mother she is English now, or Scottish in Killin
Canadian in Canada or German in Berlin.
His cousin's wife is Swedish and his uncle's wife is Greek
And he himself must surely be an international freak.

King Billy was a Dutchman and King Jamie was a Scot,
But the Prince of Wales just doesn't know if he is here or not.
Our King won't come from London town nor yet from Donegal
Nor will he be from Scotland for we'll have no king atall!
