In reply to Jim Walton: Yes, it was very good, but possibly not very well publicised - I only heard about it the day before from a poster at a climbing wall, and even then didn't realise that it was an all-day affair, being only informed about the evening session.
Which was however the one with Tony Streather and Joe Brown, also Doug Scott. What a moment - like seeing characters from the Lord of the Rings moving about and speaking, so venerable are these great figures from British climbing. Joe was fascinating, and, as one might expect, totally down-to-earth, while Tony Streather was as self-effacing as you say.
I did get to shake Tony Streather's hand, also to ask Doug Scott just how steep that snow on the Hillary step was ("quite steep when Dougal did it, pretty sugary and dangerous, especially at that height").
Still a pity about missing the earlier part of the day.
Perhaps Doug Scott can arrange to have Edward Whymper and Mallory to give the keynote lectures next time. Also VJE Ryan, I have always been fascinated by this mysterious figure who seemed to rampage around the Alps in 1906 doing an incredible series of hard serious routes, way ahead of their time, but apparently never heard of before or since. Can you get Doug to ask him?
