When and where was Doris Lessing’s story, “The Temptation of Jack Orkney,” first published?
It appeared as part of a collection in 1972 by Jonathan Cape; I think the UK edition would have pre-dated the US one, but maybe not by much.
This bibliography isn’t complete and doesn’t list it as a separate entry but elsewhere on the site it implied that none of the stories in that collection were more than 7 years old. And it may be that it’s first appearance was in that 1972 collection…
Not a very definitive answer, I’m afraid!
