Hi Davy, I thought no one was attempting it this week. I had all these answers given by sedge47 and tyrepill but, particularly in the case of vicar and victor, I just don't understand the answers so I didn't post my entry this week.
filibuster. It looks very much like sedge and tyrepill are right with their answers,but I have no idea, like yourself, as to how these answers are arrived at. Perhaps someone out there can enlighten us?
