This is deeply scary. I’m going to be on the radio, talking – live (!!!)( eeekkk!!!!) – with Jumoke Fashola about London: A Spiritual History on Sunday 20 March at about 8.40am. Here’s the link to the show. If I do well, leave reassuring comments; if I don’t please pass by in sympathetic silence.

Update: If you want to listen to me, wind the programme forward to 2 hours and 43 minutes. I’m on for about eight minutes after that.
