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

Someday we'll find it, the rainbow connection The lovers, the dreamers and me

Who said that wishes would be heard and answered when wished on the morning
star?

Someone thought of that and someone believed it 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 calls 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

Someday we'll find it, the rainbow connection, the lovers, the dreamers and me
