If you're wondering whether you've found the right version of me - there are a few of us around the world, not enough for an episode of Dr Who, but a few all the same - then I'm the one who used to be called Jon and has lived in Uganda, Swindon, Thetford, Kings Lynn, Paris, London, Singapore and Barcelona. If none of those places ring a bell, well then maybe you're an impostor. Chin, chin.
