That is a second decision to make. I agree that it sounds better.

That's wrong. The 's clitic is not like a Latin genitive inflection.
>> Since "I will be glad to attend your anniversary" is correct,
>> as is "I will be glad to attend Joe's anniversary", I know that
>> "I will be glad to attend your and Joe's anniversary" is correct.
Wrong.
> Perhaps "Joe's and your anniversary" sounds better.
It's wrong too.
Forget "you" for a moment and let's talk about Joe Clark and
Maureen McTeer, because they're famous enough to have web pages
about them where I can look up their dates. Whose anniversary
is June 30? *Joe and Maureen's*. Whose birthdays are June 5
and February 27? *Joe's and Maureen's*. (Hmm, also Joe's and
my father's. I'll have to tell him.)
In other words, if something is jointly possessed by the two
entities joined by "and", the possessive of the whole phrase
must be formed using a single 's clitic. If you make a separate
possessive form for each part, you indicate that there are two
separate possessions. So "your and Joe's" is wrong, whatever
order you write it in.
But "you and Joe's" is also wrong, because pronouns don't form
possessives using 's.
So there is no way to form the desired possessive, as I said
before, and you have to express the sentence another way.
