Malcolm Hopkins from Housman’s Bookshop and producer/ sound artist Nick Hamilton (who made the rather brilliant Foot and Mouth series) have just started a new show called Lost Steps, on Resonance 104.4fm.
I’ve nicked this blurb off their website:

“Lost Steps is a series of weekly radio programmes, exploring lost London.
Over the weeks, Malcolm Hopkins will be inviting a spectrum of invited guests to discuss and appreciate aspects of London literature and culture we seldom get to hear about; seldom reaches the mainstream media, and is often neglected as time passes by. London’s history is steeped with obscure and often clandestine reference.”

There have already been some fascinating broadcasts which you can catch-up on here: http://www.loststeps.org.uk/Broadcasts.php
I’ll be joining them for an episode in November which I had better prepare for I suppose.
