Many thanks, Drxx, Krauton and Wintonian. All done at last! I didn’t think of looking up unkindness in Chambers! I did, however, look under gang and did not find any mention of elks.
Drxx, you said yourself that you thought the clues were too difficult up to the point where you twigged the theme. My difficulty is that they were still very obscure and contrived even after I knew how to enter the answers, as is evidenced by the fact that I was still asking for help just now, about 24 hours after learning what the theme was.
As I said on the other thread, the puzzle itself was brilliant but I think it is such a shame that so many potential solvers would not get to the point of enjoying its cleverness because of the unreasonable level of difficulty in the clues. I have said the same about other Listeners in the last year or so. Not everyone who attempts the puzzles they see in the papers know about our forum, and some who do avoid it like the plague! Sorry for that reminder of the times we are living in!
Well,you did ask.
