I think if I were setting these links I'd just go for the surnames. So just as a bit of fun, I think I'd have
(9a) City in Germany divided by a wall between 1961 and 1989
(68a) - Levin, journalist and broadcaster
(74a) 'Disgusted of Tunbridge - ', author of letters to the Times
(55d) - Luther, leader of the Protestant Reformation
...and we'll see on Monday how completely wrong I am!
Thanks for your concern, LaneyB. They're due to arrive on Monday lunchtime, and at the moment the forecast for Birmingham airport is OK for the next three days, but anything can happen. I've got everything crossed (very uncomfortable!)
Very best wishes for Christmas to everyone.
