To free the Moon

Strolling one evening, once in the month of may
I came across, to my surprise, a black lake lined with clay
Being a night as this, when the moon was full and clear
I thought I'd sit and stay a while, let loose my fret and fear
Be it strange that I should find my way to old man Willow
Who's rough hide, and brambled side, I did use for my pillow
I sat and thought, bit my thumb, gave a tuneless whistle
Until a web of chilly air, did make my poor skin bristle
Getting up, to stretch and groan
I had no time to stop and moan
for then, to my horror, to my fright
I did see a most intriguingly terrible sight
The moon had fallen, cascaded from the sky
I asked myself why, why why oh why
I panicked, what could I do, no mortal could fix the heavens
all i could do, a simple man could count 123's and 7's
I scrambled to the edge, its glassy surface bending
and so I did, I set about, the moon had need of mending
Plunging in, oh brave hero, oh adventurer of the time
You would be a king of men, no need to wait in line
I marveled, I should have been born a fish, with a tail and with a fin
unfortunate then oh fool that I am, that I had never learned to swim
