Cmaj7   Gm7   G7


[VERSE 1]
Cmaj7   Gm7          Bbmaj7
       I wish I was a willow
            Ebmaj7             F7
And I could sway to the music in the wind
Cmaj7     Gm7          Cmaj7   Cmaj7/G
       I wish I was a lover
           Ab7        G7           Cmaj7
I wouldn't need my costumes and pretend

Bbmaj7             Fmaj7
  I wish I was a mountain
D7                                       G7
  I'd pass boldly through the clouds and never end
Cmaj7   Gm7          Cmaj7
  And I wish I was a soft refrain
                      Ab7      G7              Cmaj7
 When the lights were out I'd play and be your friend

[BRIDGE - nice to play on 8th fret]
Fm7            Cm7
  I strut and fret
Fm7                  Cm7
  My hour upon the stage
Fm7          Cm7
The hour is up
          Fm7              Cm7
I have to run and hide my rage
Fm7         Cm7
  I'm lost again
Fm7                    Cm7
  I think I'm really scared
Fm7                   Cm7
  I won't be back at all this time
         Fm7                  G7
And have my deepest secrets shared (whoa whoa whoa whoa whoaaaa...)

Cmaj7    Gm7         Bbmaj7
     I'd like to be a willow,
Ebmaj7                          F7
     A lover, a mountain, or a soft refrain
Cmaj7   Gm7           Cmaj7    Cmaj7/G
But I'd hate to be a grownup
             Ab7      G7           Cmaj7
And have to try and bear my life in pain

I'd     wish I was a soft refrain

When the lights were out I'd play and be your friend
