Started even later than usual, but finished in about two hours. What a lovely crossword with some amusing clues. Yes, lots of anagrams, but I like them. A couple held me up for a bit and I'm still not sure about 20 and 24d. Like you Chris I was confused about the spelling for 27ac.
FOI was 1/6 - easy anagram, LOI was 17d and 4d - it took me a while to parse the latter.
CODs 23d, 11ac and 18ac
Yippee, I have time now to plant some plants in the garden.
