This uses the tune to “London’s Burning”. Wiggle your fingers for the snakes, draw an imaginary halo around your head for St. Patrick, arm across your chest for “valiant” and in a fist for “determined”. Finally, wave an imaginary sword to vanquish the snakes.
There were too many snakes in Ireland,
When along came St. Patrick.
He was valiant and determined.
And he vanquished every one.
