Excellent session. And John, I have done some teaching (though I've never been taught to teach) but never history.
You were at Cambridge in the 70's you say, you youngster - I was there 1966-69, interesting times, student uprisings going on all over the place (but not much in Cambridge!) plus my year was the last all-male intake at my college and the last to eat in Hall from the college's appalling, smelly pre-war kitchens! But the teaching was good 
I look forward to trying yr course.
Nicola Sturgeons husband pleads guilty.
Is there a toiletry you can no longer buy and miss?
