F             Dm
Why are there so many
Bb           C7
Songs about rainbows
F                 Dm   Bb    C7
And what's on the other side
F             Dm
Rainbow's are visions
Bb        C7
But only illusions
F                 Dm        Bb    C7
And rainbows have nothing to hide
Bb    
What's so amazing is that it keeps us star gazing
Am7
What do they we think we might see?
Gm            C7
Someday we'll find it
F           Dm
The Rainbow Connection


Gm              C7           F             C7  


C7
The lovers, the dreamers and me
F             Dm
Have you been half asleep?
Bb                      C7
And have you heard the voices
F                    Dm        Bb    C7
Well I've heard them calling my name
F           Dm              Bb               C7
Is this the sweet sound that calls the young sailors?
F                  Dm         Bb    C7
The voice might be one and the same
Bb    
I've heard it too many many times to ignore it
Am7
Ooooohh and that I think it could be


Gm                 C7
Well someday we'll find it
F           Dm
The Rainbow Connection
Gm             C7           F
The lovers the dreamers and me
Gm            C7
Someday we'll find it
F         Dm
a Rainbow Connection
Gm                  C7            F
The lovers, oh, the dreamers, and me
