Song Lyrics

You're a one of a one
A one of a kind
That you only find once in a lifetime
Made to fit like a fingerprint
A code that clicks open a gold mine

They say one man's trash is another man's treasure
When I found you, it was all pretty better

Secretly, I hit the lottery 'cause you're
Brighter than all of the Northern the Lights
You speak to me, even in my dreams, wouldn't
Let you go for even the highest price

They say one man's trash is another girl's treasure
So if it's up to me, I'm gonna keep you forever

'Cause I understand you,
We see eye to eye
Like a double rainbow
In the sky
And wherever you go
So will I
'Cause a double rainbow
Is hard to find

Was a phenomenon when you came along, yeah
Chemistry was more than science
It was deafening, loud like
lightning, it was striking, you couldn't deny it

They say one man's trash is another man's treasure
The two of us together, make everything glitter

'Cause I understand you,
We see eye to eye
Like a double rainbow
In the sky
And wherever you go
So will I
'Cause a double rainbow
Is hard to find

To the bottom of the sea, I'd go to find you
Climb the highest peak to be right beside you
Every step I take, I'm keeping you in mind

(Ooh ooh ooh)

'Cause I understand you,
We see eye to eye
Like a double rainbow
In the sky
And wherever you go (I go up for you)
So will I
'Cause a double rainbow
Is hard to find

It's hard to find
Oh it's hard to find
Once in a lifetime ah

Once in a lifetime
Once in a lifetime
