Lyrics:

Statistics prove, prove that you've one birthday,

one birthday ev'ry year.

But there are three

hundred and sixty four

unbirthdays.

That is why we're gathered here to cheer.

A very merry unbirthday to you, to you.

A very merry unbirthday to you,

It's great to drink to someone and

I guess that you will do.

A very merry unbirthday to you
