Lyrics:

Happy birthday sweet sixteen
Tra la la la la la la la
Happy birthday sweet sixteen
Tonight's the night,
I've waited for
Because you're not a baby any more
You've turned into the prettiest girl I've ever seen
Happy birthday sweet sixteen
What happened to that funny face?
My Little tomboy now wears satin and lace
I can't believe my eyes
You're just a teenage dream
Happy birthday sweet sixteen
When you were only six, I was your big brother
Then when you were ten we didn't like each other
When you were thirteen, you were my funny valentine
But since you've grown up the future is sown 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 sixteen

Tra la la la la la la la
Happy birthday sweet sixteen

Tra la la la la la la la

Happy birthday sweet sixteen
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 sixteen
Tra la la la la la la la
Happy birthday sweet sixteen
Tra la la la la la la la
Happy birthday sweet sixteen
Tra la la la la la la la
Happy birthday sweet sixteen
