This stopped in 2014 and you can find the last one here.
This is what Melvyn said:
“I started doing this some time ago when – and for reasons too trivial to go into – I decided that I would dictate it as I was walking along, and (this may seem perverse) that I would not read it. (Again, too boring to go into.) I’ve loved doing it and thank you very much those of you who have responded so warmly. But this will be my last blog for In Our Time. BBC Radio has to make economies and as resources are scanter than before, it needs, rightly, to concentrate them on programmes. But I’ve enjoyed sharing my wanderings with you over the years. Thank you for reading them.”
