A law unto itself

One could meet any day in Society
Harold Acton, Tom Driberg or Rowse:
May there always, to add their variety,
Be some rather Odd Fish at The House.

Thus W. H. Auden (something of an odd fish himself) reminiscing at a Christ Church gaudy half a century ago. There have certainly been quite a lot of such fish in living memory, not least in the Senior Common Room.
