"Let Pi Be"
Sung to the Beatles " Let It Be " with new lyrics by Natakie Stopka and Ashley Steen. From Pi Day 1999

When I find myself in need of circumference
helpful Pi comes to me.
Showing me the answer,
let pi be !And in my hour of darkness
pi is continuing to puzzle me.
There won't be an answer
let pi be !Let pi be, let pi be,
it goes on to infinity,
there won't be one answer
let pi be !Among the lost and lonely mathematicians,
living in the world with me
they're looking for the answer,
let pi be !Because there is no end, they're downhearted,
but there's still a chance that they will see
there is but one answer
let pi be ! Let pi be, let pi be,
it goes on to infinity,
there won't be one answer
let pi be !

Oh, Number PI
(sung to the tune of Oh Christmas Tree)
Oh, number Pi
Oh, number Pi
Your digits are unending,
Oh, number Pi
Oh, number Pi
No pattern are you sending.
You're three point one four one five nine,
And even more if we had time,
Oh, number Pi
Oh, number Pi
For circle lengths unbending.
Oh, number Pi
Oh, number Pi
You are a number very sweet,
Oh, number Pi
Oh, number Pi
Your uses are so very neat.
There's 2 Pi r and Pi r squared,
A half a circle and you're there,
Oh, number Pi
Oh, number Pi
We know that Pi's a tasty treat.
