I love this song! I heard this song today, and it rang a bell with me. The Rainbow Connection speaks about hearing voices. 

Maybe my voices have more to do with rainbows and goodness, than evil or mental illness. I wish my voices were pretty and sweet, like rainbows.

Not to get all hippie on you, but everyone loves rainbows. This connects us all. The Rainbow Connection is a great song and a tearjerker for me. (every time) LOL

Why are there so many songs about rainbows
And what's on the other side
Rainbows are visions
But only illusions
And rainbows have nothing to hide

So we've been told
And some choose to believe it
I know they're wrong, wait and see
Some day we'll find it
The rainbow connection
The lovers, the dreamers, and me

Who said that every wish
Would be heard and answered
When wished on the morning star
Somebody thought of that
And someone believed it
And look what it's done so far

What's so amazing
That keeps us stargazing
And what do we think we might see
Someday we'll find it
The rainbow connection
The lovers, the dreamers, and me

All of us under its spell, we know that it's probably magic

Have you been half asleep?
And have you heard voices?
I've heard them calling my name
Is this the sweet sound
That called the young sailors?
The voice might be one and the same

I've heard it too many times to ignore it
It's something that I'm supposed to be
Someday we'll find it
The rainbow connection
The lovers, the dreamers and me
