[Verse 1]

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 the gold mine

[Pre-Chorus]

They say one man's trash is another man's treasure

When I found you, it was all pitter-patter

[Verse 2]

Secretly, I hit the lottery

'Cause you're brighter than all of the Northern Lights

You speak to me, even in my dreams

Wouldn't let you go for even the highest price

[Pre-Chorus]

They say one man’s trash is another girl's treasure

So if it's up to me, I'm gonna keep you forever

[Chorus]

'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

(Da-da-da-da-da)

(Da-da-da-da-da)

[Verse 3]

Was a phenomenon when you came along

Yeah, our chemistry was more than science

It was deafening, loud like lightning

It was striking, you couldn't deny it

[Pre-Chorus]

They say one man's trash is another man's treasure

The two of us together make everything glitter

[Chorus]

'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

[Bridge]

To the bottom of the sea, I'd go to find you (Oh)

Climb the highest peak to be right beside you (Oh)

Every step I take, I'm keeping you in mind

Ooh-ooh-ooh-ooh

[Chorus]

'Cause I understand you

We see eye-to-eye

Like a double rainbow in the sky

And wherever you go (And wherever you go), so will I

'Cause a double rainbow is hard to find

[Outro]

It's hard to find (Da-da-da-da-da, da-da-da-da-da)

Oh, it's hard to find (Da-da-da-da-da, da-da-da-da-da)

Once in a lifetime (Da-da-da-da-da, da-da-da-da-da)

(Da-da-da-da-da, da-da-da-da-da, da-da-da-da-da)

Once in a lifetime (Da-da-da-da-da)

Once in a lifetime (Da-da-da-da-da)
