Regarding the unclued entries - where there are 2 unchecked cells, and 2 possible letters, is there any pattern as to which goes where? I may be missing something in the entry method.
I found this both fun and a challenge. I led myself astray to begin with by using another possibility at 40 across but corrected that by using the CRIPPLING etc letters.
The usual expression is 7, 5 - the 5 being the word which links all the thematic entries - and is asscociated with the farmyard, -ing has been removed.
