St. Patrick's Day Song

I found this poem in my messy desk at school and forgot I had it from St. Patrick's Day. Better late than never.

Once upon a time
in a land of green
in a land of hills
and a clovery scene

From a fantasy story
our ancestors told
where at the end of each rainbow
you would find a pot of gold

With the sunny sky
and the rivers of glass
there lived some leprechauns
I'm tellin' you lass

Leprechauns play
on St. Patrick's Day!
