Thank you Jazzgirl, Bullfrog and Qtass001 - I wouldn't have got that one n a million years! I'm also stuck on 53a. Primitive primates (6) A_N_E_ and 25d. one of an aircraft's flying surfaces (9) for which I have T_I_P___E
Thanks, Jazzgirl. I've put inattention instead of inattentive for 35 down. I've really over-exceeded my crossword time limit today so many thanks for freeing me up to do something mundane like cleaning!!!!
Thanks jazzgirl and qtass001. I had put AYEAYE for 53a, following my dictionary definition as "a primitive primate(from Madagscar)". I should have noticed that the clue called for a plural.
