Willie Willie Harry Stee
Harry Dick John Harry three;
One two three Neds, Richard two
Harrys four five six....then who?
Edwards four five, Dick the bad,
Harrys (twain), Ned six (the lad);
Mary, Bessie, James you ken,
Then Charlie, Charlie, James again...
Will and Mary, Anna Gloria,
Georges four, Will four Victoria;
Edward seven next, and then
Came George the fifth in nineteen ten;
Ned the eighth soon abdicated
Then George six was coronated;
After which Elizabeth
And that's all folks until her death.
