Cheers Phillip, I never checked it, just took it as read that it was correct.
Also, I need to clarify another clue (I've just sent you an email about it GK).
The clue for 52 Across. I feel that both spellings of this answer are now to be accepted as correct.
On further inspection, I feel that because Syzzie used the word 'may' in his clue, it creates an air of ambiguity with the final answer word.
If it read as 'It is dull for Canuck.... Then it would qualify as a DEFINITE Definition of the word with an 'A' and the rest making up the wordplay, but because it reads 'It may be dull for Canuck..... Then that is where it makes both ends of the clue sound like the wordplay without a DEFINITE Point towards the true definitive part.
Sorry about that Syzzie, what do others think?
