Rainbow song
Walking on sunshine
Life is a rainbow
Oh, my God
Sing it for you
Ain't gonna be lonely
It's beautiful, it's colorful
A rainbow for me and you
Looking at the world
Is a window of opportunities
Feel the happiness
As a rhythm of life
Sunshine is your melody
A rainbow is harmony
Just enjoy yourself
Everyday of your life
Life is beautiful
And colorful as a rainbow
The past is gone, never mind
Live in the moment and cherish it
With passion, love and understanding
This is our world, our life, our rainbow
So let's sing it loud
And dance to the rhythm
Life is a beautiful rainbow
So let's embrace it with open arms
And make each moment count
As we dance in the rainbow
Life is beautiful
And colorful as a rainbow
The future is bright
With endless possibilities
So let's embrace it with open hearts
And make each moment count
As we dance in the rainbow
Life is beautiful, it's a rainbow for me and you.
