Lyrics:

Old girlfriend, she come walkin' down the street
When I saw her, it was like seeing a stranger, yeah
But even if I try to work it up, no emotions are there
That's when I know what you are to me
And how much I really care
Number one (number one)
Number one (number one)
You are number one with me (one with me)
Number one (number one)
You are number one with me
Blast from the past
Say, why don't you call me anymore?
It's been too long
And some nights, I need you so, oh I do
But even if I try to work it up, no emotions are there
And that's when I know what you are to me
And how much I really care
Number one (number one)
You are number one with me
Ah, number one (number one, number one)
You are number one with me, yeah
Number one (number one)
You are number one with me
Ah, number one (number one, number one)
You are number one with me
Oh (oh)
Oh (oh)
Oh (oh)
Oh (oh)
Oh (oh)
Oh (oh)

Number one! (Number one)

You (number one)
Are number one with me
Number one (number one, number one)
Yeah, you are number one with me
Oh yeah, oh yeah, oh yeah, oh yeah, oh yeah, oh yeah (number one)
You are number one with me
Number one (number one, number one)
You are, you are, you are, you are, you are, you are, you are number one with me
Number one (number one), yeah (yeah)
Ain't nobody (ain't nobody)
Ain't nobody else (ain't nobody else)
Ain't nobody (ain't nobody)
Ain't nobody else (ain't nobody else)
Nobody (nobody)
Nobody else (ain't nobody else)
Ain't nobody (ain't nobody)
Ain't nobody else (ain't nobody else)
Ain't nobody (ain't nobody)
Ain't nobody, ain't nobody, ain't nobody but you
'Cause you are number one for me (one for me)
Number one, number one, number one, number one
Number one, number one, number one, number one
Number one, number one, number one, number one
