Happy birthday dear Katrina
We hope you have a lovely day
Your father and I are oh so proud
In fact there's something he'd like to say
We've watched you grow from a beautiful baby into a beautiful girl
And as a flower of woman who has blossomed so fresh
You mean everything in the world

Happy birthday dear Katrina
We hope you have a lovely time
A few of us guys got together
And we bought you a cask of cheap white wine
There are 100 people here and you might know half of them
And the beer on the carpet won't stain
Just get drunk, fall over and embarrass yourself
Like you did last Saturday
And the one before that

You're the apple of my eye
You're the core of my life
But as the fruit turns sour
You throw up and fall down
And I sometimes wonder why
