Okay, so it wasn't a podcast it was Ian Fleming interviewing Raymond Chandler on the BBC, but it sounds just like a podcast today - a couple of writers sitting around bitching. What is genre? Can it be literature? How long does it take you to write a book?
Fleming even asks Chandler, "Where do you get your ideas?"
The interview took plce in 1958. There's about a five minute intro here giving some background and then the interview starts. It's really worth listening to the whole thing.

I think it's interesting when Chandler says there are no California novelists worth talking about no one mentions John Steinbeck.
