I was in my first year at secondary school, so I must have been about eleven. I'll tell you an interesting thing actually.

Someone who was in my class at school came up to me knowing that I was even then a bit of a Doctor Who fan, and said 'What's the Doctor Who story that's being filmed in Cambridge?' because his older brother was at Cambridge University. I didn't know anything about it at the time because this was obviously something that was still in the works, but he said, 'Oh yes, there's a scene where Doctor Who goes along on a bicycle because my brother was watching out of the top window." So I was waiting for this to come up on TV and it never did. So I did hear about Shada quite early on, I suppose.
