Thanks, you're a life (and mind) saver! Just a few queries though...
21. I get in now from the def'n and see where the initials C.K. and 'night' bits come from, but where does the 'arpet' come from?
39. Now that my direction of thought is on the right track, I don't think 'SPORK' works as you wouldn't be able to cut your Sunday Roast with a spoon/fork combo ie you'd need a knife/fork combo which I see from a bit of goggling is a 'KNORK'. What do you all think? The pic on this website has me convinced... http://www.knork.net/
Thanks for the multiple answers on 51. I still can't find any reference anywhere to either being a nickname for the bird. A bit of googling makes me lean toward the Bushman's version though, John(from Arran): see http://www.cinoa.org/art-and-antiques/detail/48283
Can't believe I couldn't see the anagrams in 46 &66 - shows how burned out I am with it all, and I don't think I'd ever have got the Isle of Man reference!
