Been in Cambrian, Glyn Ceriog today, did some cleaning and found myself singing this.
Little arrows on the ceiling, little arrows on the walls.
If I catch you spraying arrows, I kick you in the *****
If you come in with a spray can, it proves that you know nought
Follow the flow of water, it always takes you out.
(Chorus)
You could be in some trouble though, if the mine is dry.
But looking for the daylight, is always worth a try
(Chorus)
A straight drive from the portal, with daylight still in sight
A bloody silly arrow, pointing to the light.
Just about sums it up.
My avatar is a poor likeness.
