The Last Plantagenet Monarch

Richard of York was a plantagenet monarch,
his bones were found in a Leicestershire car park.
Ever since he passed and died
his spirit's been searching for a park 'n ride.

Here's some trivial information,
he had major skeletal malformation.
Forever known as the hunchback king,
'My kingdom for a horse!' he used to sing.

Two young princes (one an heir) died
both alleged victims of his ignominious regicide.
His gaunt frame was oft enrobed in purple silk
He should have feasted on biscuits from Cadbury Dairy Milk.
