Say it's only a paper moon
Cm7      F9    Bbmaj7       (F9)
hanging over a cardboard sea
Bb7                Eb6   Edim
but it wouldn't be make-believe
   F9              Bbmaj7   F9
if you believed in me

Yes, its only a canvas sky
hanging over a muslin tree

if you believed in me

Without your love
       Cm7   F7      Bbmaj7
it's a honky-tonk parade
Eb6      Edim  B/F  G7
without your love
       Cm7                  F7
it's a melody played in the penny arcade

It's a barnum and bailey world

if you believed in me

if you believed in me
