Tonight, Tonight,
I'm waitin' for,
Because your not a baby anymore,
You've turned into the prettiest girl I've ever seen,
Happy Birthday Sweet 16!

What happened to,
That Funny face,
My little Tomboy now,
Where's that Turnup legs,
I can't believe my eyes,
You're just a teenage dream,
Happy Birthday Sweet 16!

When you were only 6,
I was your Big Brother,
Then when you were 10,
We didn't like each other,
When you were 13,
You were my Funny Valentine,
Since you've grown up,
The future is sewn up,
From now on you're gonna be mine so,

If I should smile,
With sweet Surprise,
It's just that you've grown up,
Before my very eyes.
You've turned into the Prettiest girl I've ever seen,
Happy Birthday Sweet 16!
