Thanks to everyone who turned up to see my brother's fascinating lecture last night. It really was a superb evening. As you are aware, Andrew was only able to get through the first part of the lecture due to the sheer amount of information he had to share, so we have decided to have him back to talk a second time in October. The second half is quite different to the first, so don't worry if you missed the first part. The planned documentary eve which was set to take place in October will be postponed till early 2013.
