Andrew - 'Fraid I can't answer your first question but it sounds like he'd have been happy with either. The quote comes from "31 December, 1947," The Table Talk of W.H. Auden, compiled by Alan Ansen, ed. Nicholas Jenkins published in New York, by Sea Cliff Press around 1989/1990. Have I wrongly attributed?
You only have to let the soft animal of your body
love what it loves.

Dear Damellon,
I agree: he would be happy in either .
I don't have "31 December, 1947" in my Auden stuff (at least, what I've trawlled through so far!).
All of which serves to say I need to read more of the great man.
Best wishes for 2008,
Andrew.
