Well I finally finished. I used to like Paul, but he has got much more difficult. I finally got the PDM for 26,27 when I decided how 15d would end. Like others I didn't like 22d.
I can't fully parse 13ac,22ac and 15d.
I couldn't parse 17ac until reading some of the threads above - thank you Jono.
I was puzzled by 24ac as part of the longer clue 8,10,24. I've never heard of this phrase. 21d was a new word to me too.
My FOI was 7ac, LOI was 21d and CODs 3d (though I got this wrong at first) and 23d
