Well what a surprise
I finished in record time for me and found it comparatively easy. My FOI was 14ac (an obvious anagram). I can't understand why it took some of you so long. In fact there are lots of anagrams in this crossword. Of course it helps that I'm familiar with 28ac from the Shakespeare and I know 1ac. I did have to look up seahorses in 3d to get the answer.
There are five I couldn't completely parse or am not 100% sure of.
5ac I don't like refuse for the definition.
12ac was my LOI as I was stuck on all the Atkinsons I could think of and the right one didn't come to mind straight away, though I know the horse.
18ac I had trouble parsing, so thanks to the explanation in the stream above.
8d I couldn't see where two of the letters came from
6/21 I've got an answer from the crossers, but don't know why it is right.
Normally I'd share my concerns with my friend in Sheffield, but she is having major surgery today, so won't be doing to crossword or available tomorrow for a discussion.
My CODs were 19d. The Paulian answer brought a smile to my lips. I also liked 23d, 9ac and 25ac
Finally, can anyone explain why the answer to 18d (A) lot in today's quick crossword is "sight". I can't see it or find a definition in Chambers.
