I have managed to get most of this done including thematic cells and the necessary transposition. However I have been stumped by the last two clues for a while now and would be grateful if someone could put me out of my misery. One is the pillowcase clue (18a) alluded to in an earlier post for which I have ??ar. The other is 18d, Steer old Gort’s... for which I have ?e?f. Have I gone wrong somewhere or am I just missing two simple words for which I will doubtless kick myself? Thanks in advance.
