Lyrics by e.y. (yip) harburg

I never feel a thing is real
When I'm away from you
Out of your embrace
The world's a temporary parking place

Mmm, mm, mm, mm
A bubble for a minute
Mmm, mm, mm, mm
You smile, the bubble has a rainbow in it
[ Lyrics from: http://www.lyricsfreak.com/h/harold+arlen/its+only+a+paper+moon_20064353.html ]
Say, it's only a paper moon
Sailing over a cardboard sea
But it wouldn't be make-believe
If you believed in me

Yes, it's only a canvas sky
Hanging over a muslin tree
But it wouldn't be make-believe
If you believed in me

Without your love
It's a honky-tonk parade
Without your love
It's a melody played in a penny arcade

It's a barnum and bailey world
Just as phony as it can be
But it wouldn't be make-believe
If you believed in me
