during my brief stint as editor I couldn't even get other officers to provide me with a half A5 page precis of the talk!

It would be good if your suggestion was followed up but I suspect as Nigel has hinted, that for those with fully scripted talks then they have either presented the material previously at an Antiquarian meeting (and will thus sometime appear in the more presitigeous Proceedings) or it is a dry run prior to an Antiquarian Soc outing.
