As an accompanying thread to “Secrets of the Pop Song - excellent BBC TV series”, I would also recommend a documentary that is currently being broadcast on BBC radio, but does not appear to be part of a series:

making tracks: “Critic and cultural commentator Paul Morley returns to the Basing Street Studios, home to Island Records and then his own ZTT label. These were the very rooms in which everyone from Led Zeppelin, Cat Stevens and Bob Marley through to Frankie Goes to Hollywood, the Art of Noise and Grace Jones recorded some of their most iconic albums. In the company of Island's Chris Blackwell and ZTT's Trevor Horn, as well as legendary engineer Tony Platt, Paul attempts to find out what it was about this particular space that led to some of the most memorable recordings of the 70s and 80s”

..and you should be able to listen to this wherever you are!
