Paper Moon lyrics

Say its only a paper moon
Sailing over a cardboard sea
But it wouldnt be make believe
If you believed in me

And its only a canvas sky
Hanging over a muslin tree (oh,yeah)
But it wouldnt be make believe
If you believed in me

Without your love
Its a honky-tonk parade
Without your love
Its a melody played in the penny arcade

Its barnum and bailey world
Just as phony as it can be (I know)
But it wouldnt be make believe
If you believed in me
