Well I preferred Paul's horror of last week. I've finished but I'm left with some parsing issues and a bit of cheating.
Parsing issues:
18ac I don't understand where the fellow travellers come in
20ac?
27ac?
1d I think I don't know this 3 letter word for cock, though I'm sure its a source of energy
7d Where do the piggies come in?
14d I can't see what greyfriars bobby had to do with this
29d I can't see why this means sample?
16d don't like the parsing
I didn't know the word in 13d
Thanks for the hints above
FOI was 26ac even though I'd never come across this word before
LOI 14d
COD I liked 30ac and several others
Back to my chores
