《Rainbow》的歌詞是：
Verse 1:
Looking out my window
At the raindrops on the ground
But then I see something
That makes me feel all right
Chorus:
It's a rainbow, it's a beautiful thing
A rainbow, it's all around me
When everything seems to be gray
A rainbow, it's a beautiful thing
Verse 2:
I might be feeling sad
But I know that it's not for long
Cause I know there's a rainbow
Up in the sky for me to see
Chorus:
It's a rainbow, it's a beautiful thing
A rainbow, it's all around me
When everything seems to be gray
A rainbow, it's a beautiful thing
Bridge:
Life is like a rollercoaster
Up and down and round and round
But in the end it's worth it
Cause you know there's gonna be a rainbow
Chorus:
It's a rainbow, it's a beautiful thing
A rainbow, and I'm holding on to it
And when everything seems to be lost
I'll find my way to the rainbow
Cause it's a beautiful thing
(Beautiful thing)
Outro:
It's a rainbow, gotta gotta gotta gotta gotta gotta hold on to it.
