Thank you again Malone, Jono and Jack Aubrey. I was trying to overegg the pudding by further changing the 3, 6. It is now all complete but I won't submit as I have had a lot of help with it. It was as everybody else has said a cracking puzzle.
There have been references in this thread (and in previous threads) to the big three of the weekend. My weekend includes a big 4, I.e. The Listener, the EV, the Mephisto and the Azed. Which one of these do you guys regard as not being included in your big 3? Also in this EV I have been unable to parse 27. Any hints?
