OK, got to get this written down and out of my head.
End of Good Omens 3 after whatever happens. There is an old rundown cottage ìn South Downs (that no-one remembers being renovated) , the neighbours approach the new occupants as the get out of their Bentley.
When asked if their the new owners Aziraphale answers that they are and introduces Crowley nervously, then with a look of determination says "my Husband"
Crowley beaming says "Aziraphale, my Angel"
After the neighbours leave Crowley asks, "so, Husband is it", "well yes , may as well make it official " , "quite right ". Each miracle a band for each other as they slow dance , surrounded by bookshelves and plants , while 'Nightingale Sang in Berkeley Square' plays on a record player.
The cottage may or may not be called Alpha Centauri , or Nightingale or something
