I will once more trot out my predictable reply...
This will never be solved to everyone's satisfaction, there are many ways in which people view this. For myself, I consider it courtesy to honour what the quiz setter asks (I do realise Butterbean asked for a clue by the way) - do I ask family, use Google or my pile of reference books, of course I do.
I may have this quiz - if so it will be in the December pile, have a few months worth to get through before then.
Happy quizzing, it should be fun not lead to arguments.
