Thanks all for the help with the clues.
We don't have Christmas holidays where I live, and I couldn't take the time off to try and complete this superb offering by the Monkey Puzzle man earlier. But, I've got it licked now and am again amazed at the breadth of the man's knowledge and the truly convoluted clue setting.
Wish you all a belated Merry XMas and a Happy 2011!
