Thanks for starting this thread Malone. I have a question on one clue: 20 - Rather dismal indeed in shameful glow.
If the answer describes my beloved Cardiff Rugby team's jersey and is built around an embarrassed response how does 'indeed' fit it? Is 'I' in some way an abbreviation?
I shall look again as this and the other thread develop but I have concluded that this puzzle is too difficult. If any setters are following this discussion I would simply say that the cold clues are too hard. There would be enough stretch in the puzzle for me if they were a lot easier.
I say this not as a complaint, merely an observation. I accept that the higher level of solvers need a challenge. I do enjoy the effort and benefit from the thread.
