I believe "Coffee in a Carboard Cup" is originally from the musical "70, Girls, 70" and then used in "...World Goes Round".
You may be able to find it in a Kander/Ebb compilation book or in one of those shows music books.

If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
