It certainly was worth waiting Lumen! 32a unlocked things for me and confirmed that I was OK with the SE corner. Oddly, I'd put the right entries in at 4a and 15d quite early on and the grid quickly filled with all the cold solves and that gave me the few I had missing. Still a few unparsed and therefore a couple of missing letters but I have the instruction.
I think I'll leave it there and see what others ask, rather than google-bashing the words, given some are incomplete and what has been said earlier.
Thanks again kind helpers!
