Celebrate the Day

Let's celebrate the day of your birth
When you joined all the creatures on this earth
The chickie said "Peep," the lamb said "Baaah"
When you arrived, you hollered "Waaaaahh"
Now we're here to wish you
A very happy birthday
A merry full of mirth day
A welcome to this earth day
Happy Birthday to you!
How old are you today?
How old will you be in one year?
How old will you be in ten years?
How old were you one year ago?
My how you've grown!
Repeat verses 1 and 2
