Lyrics:

[Intro: All]
(Ooh) Oh-oh
(Ooh) Yeah yeah
Na na na na na na na
Na na na na na na na

What is love? 'Cause baby, I don't know
I got a funny feeling in my heart
If this is love, it feels like butterflies
So tell me, baby, is this how it starts?

[Pre-Chorus: Jo]
I know I've never felt like this before
You're like a drug, you got me wanting more
I've got to let you know
I've got to let you know

You're, you're my number one
I'd do anything for you
Catch the rain from the sky
Even hold back the tide for you, baby, baby
You're, you're my number one
With you, I know I belong
I put the radio on and it's always playing our song

[Post-Chorus: All]
Na na na na na na na
Na na na na na na na

Tell me what, what have I gotta do?
'Cause I wanna lay a claim on you
To make you mine, for now and for all time
So tell me baby, what I gotta do, yeah

[Pre-Chorus: Jo]
I know I've never felt like this before
You're like a drug, you got me wanting more
I've got to let you know
I've got to let you know

You're, you're my number one
I'd do anything for you
Catch the rain from the sky
Even hold back the tide for you, baby, baby
You're, you're my number one
With you, I know I belong
I put the radio on and it's always playing our song, yeah

[Bridge: Jo]
There ain't nothing I wouldn't do, oh-oh
I'd walk on waves just to be with you
Baby, baby

You're, you're my number one (you are, you are, you're my number one)
I'd do anything for you
Catch the rain from the sky
Even hold back the tides for you, baby, baby
You're, you're my number one (you are, you are, you're my number one)
With you, I know I belong
I put the radio on and it's always playing our song, hey
You're, you're my number one (oh, you're my number one)
I'd do anything for you
Oh-oh, ooh
