Another quiz, the connection this time is in the spelling of the answers. It should be obvious once you've got a couple!. I would have given 26 questions, but I was stuck for two of the answers (Hint, Hint!)
As usual PLEASE Do Not put answers in the thread. I will respond to PMs claiming first/best scores, and comments (but not answers) can be put here.
The questions have been re-arranged so that they are not (generally) in alphabetical order.
