Lyrics:

A very merry unbirthday
To me
To who?
To me
Oh, you

A very merry unbirthday
To you
Who, me?
Yes, you
Oh, me
Let's all congratulate us with another cup of tea
A very merry unbirthday to you

Now statistics prove
Prove that you've one birthday
Imagine just one birthday every year
Ah, but there are 364 unbirthdays
Precisely why we're gathered here to cheer

Why then today is my unbirthday too
It is
What a small world this is
In that case

A very merry unbirthday
To me?
To you
A very merry unbirthday
For me?
For you
Now blow the candle out, my dear
And make your wish come true
A very merry unbirthday to you
