The best Doctor we never had

I was reading about the music hall legend Dan Leno last night, and found myself regretting that Doctor Who wasn't around in the 1890s to avail itself of the services of the greatest comedian of his era. Where's the secret of time travel when you need it?

And, on the subject of the good Doctor, I shall be signing copies of my Terry Nation book at a Doctor Who event in Norwich this Sunday afternoon. If you look out for the long queues - they'll be for Colin Baker. I'll be the one sitting quietly in the corner.
