So, I used to think the advice on this board was "ladies first, and never separate a man from his last name."
So, I thought it went:
Mrs. Jane and Mr. John Doe.
But. Now people are throwing around:
Mr. and Mrs. John Doe
Which one is it for real? Because I've been working on my invitation spreadsheet all evening and I just finished 288 names the FIRST way.

I think the way you did it is just for when you're using both first names on an envelope..

Collecting ladies' preferred title and name is part of collecting addresses. It is a good idea to start early: if you still have peoples' Christmas card envelopes around, you might be lucky enough to find a few that have return-address labels that include their names and titles. You resort to standard form only when you really do not know the lady's preference.
The standard up until the 1980s was "Mr and Mrs John Smith". By the late 1980s many diplomatic protocol manuals were recommending "Ms Jane Smith and Mr John Smith", with Jane and John's names in alphabetical order. Yay women's liberation. The most common usage in first social circles from what I have seen is "Mr John Smith and Mrs Jane Smith" or Mr John and Mrs Jane Smith". If you search the internet you can find recent invitations to the White House or Rideau Hall and so on, that use one of these forms.
